Bismuth Neodecanoate is a widely used organic bismuth compound, mainly used in industrial fields such as coatings, inks, plastics and rubbers. Its main function is that it acts as a catalyst and stabilizer, which can significantly improve the performance of the product, extend the service life, and has obvious advantages in environmental protection. In recent years, with the increasing demand for low-odor products by consumers, how to achieve low odorization while maintaining the excellent performance of bismuth neodecanoate has become an important topic in the industry.

1. Chemical structure and stability

The chemical structure of bismuth neodecanoate consists of bismuth ions and three neodecanoate roots, which imparts good thermal and chemical stability. Compared with other organic bismuth compounds, bismuth neodecanoate is not easy to decompose at high temperatures and can maintain activity over a wide temperature range. In addition, the ester bonds of bismuth neodecanoate are relatively stable and are not prone to hydrolysis, so they also show good stability in humid environments.

2. Catalytic Performance

Bissium neodecanoate is a highly efficient organic bismuth catalyst and is widely used in polymerization reactions such as polyurethane, epoxy resin, and acrylate. Its catalytic mechanism mainly reduces the reaction activation energy through the interaction between bismuth ions and the active groups in the reactants, thereby accelerating the reaction process. Studies have shown that the catalytic efficiency of bismuth neodecanoate is higher than that of traditional tin catalysts, and will not produce harmful by-products, and meet environmental protection requirements.

3. Environmental Friendship

One of the great advantages of bismuth neodecanoate is its environmental friendliness. Compared with traditional heavy metal catalysts such as lead and cadmium, bismuth neodecanoate does not contain heavy metal elements and will not cause pollution to the environment. In addition, bismuth neodecanoate has good biodegradability and can gradually decompose into harmless substances in the natural environment, which meets the requirements of modern green chemical industry.

4. Odor problems

Although bismuth neodecanoate has many advantages, it still has certain odor problems during its use. Bismuth neodecanoate itself has a slight ester odor, and in some applications, especially at high temperatures or high humidity conditions, trace amounts of volatile organic compounds (VOCs) may be released, causing odors in the product. This problem not only affects the user experience of the product, but may also have adverse effects on the production environment and workers’ health. Therefore, how to effectively reduce the odor of bismuth neodecanoate has become an important direction in current research.

Odor source analysis

The odor problem of bismuth neodecanoate mainly stems from the following aspects:

1. Raw material residue

In the synthesis of bismuth neodecanoate, if the raw materials (such as neodecanoate or bismuth salt) fail to react completely, a small amount of unreacted raw materials may remain in the final product. These residues are prone to evaporation under high temperature or humidity conditions, resulting in odor. Studies have shown that the residual amount of neodecanoic acid is positively correlated with the odor intensity of the product, so controlling the purity of the raw materials and reaction conditions is the key to reducing odor.

2. By-product generation

The synthesis reaction of bismuth neodecanoate is not completely ideal and may be accompanied by some side reactions. For example, during the transesterification reaction, small amounts of low molecular weight ester compounds or other volatile organic compounds (VOCs) may be generated. Although these by-products are low in content, they may still have a significant impact on the odor under certain conditions. By optimizing the reaction process and reducing the generation of by-products, the odor of the product can be effectively reduced.

3. Storage Conditions

As bismuth neodecanoate is exposed to high temperature, high humidity or strong light during storage, a slow decomposition reaction may occur, releasing traces of volatile organic matter. In addition, long-term storage may cause the ester bonds in the product to break, resulting in free neodecanoic acid or other low molecular weight compounds, thereby aggravating the odor problem. Therefore, reasonable storage conditions are crucial to keeping the product low in odor.

4. Application Environment

The application environment of bismuth neodecanoate will also have an impact on its odor. For example, during high temperature curing or processing, bismuth neodecanoate may react with moisture or other substances in the air to produce volatile organic matter. In addition, solvents or additives used in certain applications may also interact with bismuth neodecanoate, resulting in an increase in odor. Therefore, in practical applications, selecting suitable solvents and additives and optimizing the processing technology can effectively reduce the generation of odors.

Recipe Optimization Strategy

To achieve low odorization of bismuth neodecanoate, formulation optimization is a crucial step. By adjusting the individual components in the formula, the generation of odor can be effectively reduced while maintaining the excellent performance of the product. Here are several common recipe optimization strategies:

1. Select low-odor ingredients

In the synthesis of bismuth neodecanoate, the selection of high-quality raw materials is the basis for reducing odor. Studies have shown that the use of high-purity neodecanoate and bismuth salts can significantly reduce the residue of unreacted raw materials, thereby reducing the odor of the product. In addition, choosing low-odor solvents and additives is also key. For example, some organic solvents (such as A and Dimethyl) have a strong odor, while the use of odorless or low odor alternatives (such as ethyl ester, isopropanol) can effectively improve the odor performance of the product.

Raw Material Type	Traditional Choice	Low odor alternatives	Pros
Neodecanoic acid	Industrial grade neodecanoic acid	High purity neodecanoic acid	Reduce unreacted raw material residues and reduce odor
Bissium Salt	Bissium oxide	High purity bismuth salt	Improve reaction efficiency and reduce by-product generation

Adjuvant	Traditional plasticizer	Odorless plasticizer	Do not affect product performance and reduce odor generation

2. Add deodorant

Add an appropriate amount of deodorant to the formula can effectively adsorb or neutralize volatile organic matter, thereby reducing the odor emission. Commonly used deodorants include porous materials such as activated carbon, molecular sieve, and zeolites. They can capture odor molecules through physical adsorption. In addition, certain chemical deodorants (such as amine compounds, metal salts) can neutralize odor sources through chemical reactions to achieve better deodorization effects.

3. Optimize the amount of catalyst

The amount of bismuth neodecanoate is used as a catalyst, and its use directly affects the performance and odor of the product. Excessive catalyst may lead to side reactions and increase odor production. Therefore, rationally controlling the amount of catalyst is the key to achieving low odorization. Studies have shown that by precisely controlling the amount of bismuth neodecanoate, the production of odor can be minimized while ensuring the catalytic effect. In addition, it is also possible to consider using composite catalysts or heterogeneous catalysts to improve catalytic efficiency and reduce the amount of single-phase catalysts.

Catalytic Type	Pros	Disadvantages

Composite Catalyst	High catalytic efficiency and low odor	Complex preparation, high cost
Hundred-phase catalyst	Good stability and low odor	The reaction rate is slow and the scope of application is limited

4. Introduce synergistic effects

By introducing other functional additives, synergistic effects can be produced with bismuth neodecanoate to further reduce the odor. For example, some antioxidants and anti-ultraviolet agents can not only improve the weather resistance of the product, but also inhibit the decomposition reaction of bismuth neodecanoate and reduce the generation of odor. In addition, certain surfactants can improve the dispersion of bismuth neodecanoate, making it more evenly distributed in the system, thereby reducing odor problems caused by excessive local concentrations.

The following are several common production process improvement strategies:

1. Reaction Condition Control

The synthesis reaction conditions of bismuth neodecanoate (such as temperature, pressure, reaction time, etc.) have an important influence on the odor of the product. Studies have shown that higher reaction temperatures and longer reaction times may lead to the occurrence of side reactions and increase the production of odors. Therefore, by precisely controlling the reaction conditions, the generation of odor can be minimized while ensuring product quality.

Reaction Conditions	Optimization measures	Effect
Temperature	Reduce the reaction temperature	Reduce side reactions and reduce odor
Suppressure	Control reaction pressure	Improve reaction efficiency and reduce by-product generation
Reaction time	Short reaction time	Reduce side reactions and reduce odor
Agitation speed	Optimize stirring speed	Promote uniform mixing and reduce local odor

2. Regulation and purification

In the synthesis process of bismuth neodecanoate, distillation and purification are an important step. Unreacted raw materials, by-products and other impurities can be removed through distillation, thereby improving the purity of the product and reducing the generation of odor. Studies have shown that the use of multi-stage distillation technology can more effectively separate the target product and ensure the low odorization of the product.

Regulation Method	Pros	Disadvantages
Single-stage distillation	Simple operation, low cost	The separation effect is limited and the smell is relatively large
Multi-stage distillation	Good separation effect and small smell	Complex equipment, high cost
Molecular distillation	High separation accuracy and extremely small odor	The equipment is expensive and difficult to operate

3. Vacuum drying

In the post-treatment process of bismuth neodecanoate, vacuum drying can effectively remove moisture and other volatile substances from the product, thereby reducing the production of odor. Studies have shown that vacuum drying can achieve efficient dehydration and degassing at lower temperatures, avoiding side effects caused by high-temperature treatment. In addition, vacuum drying can improve product stability and extend storage time.

Drying method	Pros	Disadvantages
Atmospheric pressure drying	Simple equipment, low cost	High temperature, easy to produce odor
Vacuum drying	Low temperature, small smell	Complex equipment, high cost
Free-drying	Extremely low temperature and very small odor	The equipment is expensive and difficult to operate

4. Packaging and Storage Optimization

The packaging and storage conditions of bismuth neodecanoate also have an important impact on its odor. The use of sealed packaging can effectively prevent the invasion of external air and moisture, prevent the product from decomposing during storage, thereby reducing the generation of odor. In addition, choosing a suitable storage environment (such as low temperature and light protection) can also extend the shelf life of the product and maintain its low odor characteristics.

Packaging Method	Pros	Disadvantages
Plastic barrel	Low cost, easy transportation	Poor sealing, easy to leak
Metal Can	Good sealing, moisture-proof and oxidation-proof	High cost and heavy weight
Vacuum Packaging	Excellent sealing and small smell	Complex equipment, high cost

Addant selection and application

In the application of bismuth neodecanoate, selecting the appropriate additive can effectively improve the odor performance of the product while improving its performance. the followingAre several common additives and their application effects:

1. Defoaming agent

In the application of bismuth neodecanoate, the production of foam will not only affect the appearance of the product, but may also lead to an increase in odor. Defoaming agents can effectively eliminate foam and reduce the spread of odor. Commonly used defoaming agents include silicone oils, polyethers and mineral oils, which have different defoaming mechanisms and scope of application.

Introduction

Bismuth Neodecanoate, as an important organometallic compound, has a wide range of applications in many industrial fields. It not only shows excellent performance in the fields of catalysts, coatings, plastic additives, etc., but also shows great potential in the pharmaceutical and electronic industries. In recent years, with the increasing global demand for environmentally friendly and efficient production, how to reduce the production cost of bismuth neodecanoate and improve production efficiency has become an urgent problem.

The chemical formula of bismuth neodecanoate is Bi(C10H19COO)3 and the molecular weight is 684.52 g/mol. It is a white or slightly yellow crystalline powder with a melting point of about 100-110°C and has a low solubility, but has good solubility in organic solvents. Its main components are bismuth ions and neodecanoate ions, which have good thermal stability and chemical stability. These properties allow bismuth neodecanoate to exhibit excellent performance in a variety of application scenarios, especially in catalytic reactions, which can significantly improve the reaction rate and selectivity and reduce the generation of by-products.

Although bismuth neodecanoate has many advantages, its production process is relatively complex, involving multi-step reactions and fine operation control, resulting in high production costs. In addition, traditional production processes have problems such as high energy consumption and low raw material utilization, which limits their large-scale application. Therefore, exploring new production technologies and optimizing existing processes to reduce production costs and improve efficiency has become a hot topic of current research.

This article will analyze the ways in which bismuth neodecanoate reduces production costs and improves efficiency from multiple perspectives. First, we will discuss the production process of bismuth neodecanoate in detail and its existing problems, then introduce the research progress of relevant domestic and foreign literature, and then propose specific optimization plans and technical improvement measures. Through systematic analysis and discussion, it is hoped that it can provide a valuable reference for the production and application of bismuth neodecanoate.

The production process of bismuth neodecanoate and its existing problems

The production process of bismuth neodecanoate usually includes the following key steps: raw material preparation, synthesis reaction, separation and purification and post-treatment. Each step has an important impact on the quality and production cost of the final product. The following are the detailed production process and its existing problems:

1. Raw material preparation

The main raw materials for bismuth neodecanoate include bismuth sources (such as bismuth oxide, bismuth chloride, etc.) and neodecanoic acid. The selection and quality of bismuth source directly affect the progress of subsequent reactions and the purity of the product. At present, commonly used bismuth sources include bismuth oxide (Bi2O3), bismuth chloride (BiCl3) and bismuth nitrate (Bi(NO3)3). Among them, bismuth oxide is a common source of bismuth because it is relatively low in price and easy to obtain. However, bismuth oxide has a low solubility and requires higher temperatures and longer time to completely dissolve, which increases energy consumption and reaction time.

Neodecanoic acid is a long-chain fatty acid, usually through transesterification or directPreparation by synthetic method. The quality and purity of neodecanoic acid have a great impact on the final product, especially when its purity is insufficient, impurities may be introduced, affecting the performance of bismuth neodecanoate. In addition, the synthesis process of neodecanoic acid also requires a large amount of energy and chemicals, increasing production costs.

2. Synthesis reaction

The synthesis reaction of bismuth neodecanoate is usually carried out by acid-base neutralization or coordination reaction. The acid-base neutralization method is to mix bismuth source with neodecanoic acid in an appropriate solvent to facilitate the progress of the reaction by adjusting the pH. The advantages of this method are simple operation, low equipment requirements, but slow reaction rates and easy to produce by-products, such as hydrolysates and unreacted raw materials. In addition, moisture generated during the reaction will affect the purity and stability of the product and require additional drying steps.

The coordination reaction rule is to form bismuth neodecanoate through the coordination between bismuth source and neodecanoic acid in an organic solvent. The advantages of this method are that the reaction rate is faster and the product purity is higher, but the requirements for solvent selection and reaction conditions are higher, which increases process complexity and cost. In addition, certain organic solvents are volatile and toxic and can cause harm to the environment and operators.

3. Isolation and purification

The isolation and purification of bismuth neodecanoate is a critical step in ensuring product quality. Commonly used separation methods include filtration, centrifugation, evaporation and recrystallization. Due to the low solubility of bismuth neodecanoate, problems of incomplete precipitation or residual impurities are prone to occur during the separation process. Especially when the reaction system contains more by-products, the difficulty of separation further increases, resulting in a decrease in product yield. In addition, the solvents and additives used during the separation process will also increase production costs and cause pollution to the environment.

4. Post-processing

Post-treatment mainly includes steps such as drying, crushing and packaging. Drying is an important part of removing moisture from products. Commonly used drying methods include vacuum drying, spray drying and freeze drying. Although vacuum drying can effectively remove moisture, the equipment investment is large and the energy consumption is high; the spray drying speed is fast, but the product particle size distribution is uneven; freeze-drying is suitable for heat-sensitive products, but the cost is high. Crushing and packaging are designed to meet the needs of different customers, but these steps also increase production time and cost.

Summary of problems existing in existing production processes

By analyzing the bismuth neodecanoate production process, the following main problems can be found:

High cost of raw materials: The prices of bismuth sources and neodecanoic acid fluctuate greatly, and the purity of some raw materials is insufficient, which affects product quality.
High energy consumption: High temperature and pressure are required during the reaction process, resulting in increased energy consumption and increased production costs.
Slow reaction rate: The reaction rate of traditional processes is slow and the production cycle is long, which cannot meet the needs of large-scale production.
Many by-products: By-products are easily produced during the reaction, which affects product purity and yield.
It is difficult to separate and purify: During the separation process, there is easy to cause incomplete precipitation or residual impurities, resulting in a decrease in product yield.
Environmental Pollution: Some organic solvents and additives are volatile and toxic, which may cause harm to the environment and operators.

The existence of these problems not only increases the production cost of bismuth neodecanoate, but also limits its application in more fields. Therefore, optimizing production processes, reducing production costs and improving efficiency has become an urgent problem to be solved at present.

They found that ultrasound can accelerate the reaction of bismuth source with neodecanoic acid in a short period of time, significantly increasing the reaction rate and product yield. In addition, ultrasonic waves can reduce the generation of by-products and improve the purity of the product. The big advantage of this method is that it does not require high temperature and high pressure conditions, reduces energy consumption and equipment requirements, and is suitable for large-scale production.

Another study published by Smith et al. (2020) in Chemical Engineering Journal explores the possibility of synthesis of bismuth neodecanoate using microwave heating technology. Microwave heating can directly heat reactants at the molecular level, avoiding heat transfer losses in traditional heating methods, thereby improving reaction efficiency.

They use density functional theory (DFT) calculations and experimentsVerification reveals the coordination mechanism between bismuth ions and neodecanoate ions. Studies have shown that a stable hexa-coordinated structure is formed between bismuth ions and neodecanoate ions. This structure not only enhances the thermal stability of the product, but also improves its catalytic performance. In addition, the study also found that the intermediates formed during the reaction have an important impact on the purity and yield of the final product, so optimizing the production conditions of the intermediate is the key to improving product quality.

1.3 Technical means to reduce costs and improve efficiency

In order to reduce the production cost of bismuth neodecanoate and improve efficiency, foreign scholars have proposed a variety of innovative technologies. For example, Johnson et al.

They found that solid acid catalysts were able to catalyze the reaction of bismuth source and neodecanoic acid under mild conditions, avoiding the by-products produced in traditional acid-base neutralization methods. The experimental results show that when using solid acid catalyst, the reaction time is shortened by 50%, and the product yield is increased by 10%.above. This method also has the advantages of simple operation, environmental protection and pollution-free, and is suitable for large-scale production.

They revealed the hydrolysis process of bismuth neodecanoate in water through in situ infrared spectroscopy and quantum chemistry calculations. Studies have shown that the hydrolysis reaction of bismuth neodecanoate is a gradual process, first of which the bismuth ions coordinate with water molecules, and then gradually decompose into bismuth oxide and neodecanoic acid. This research provides a theoretical basis for the development of a more stable new bismuth neodecanoate.

2.3 Technical means to reduce costs and improve efficiency

In order to reduce the production cost of bismuth neodecanoate and improve efficiency, domestic scholars have also proposed a variety of innovative technologies. For example, Zhao Liu et al.

Experimental results show that when separated using nanofiltration membrane, the product purity reached more than 99.5%, and the separation efficiency was 20% higher than that of traditional methods. In addition, the nanofiltration membrane also has the advantages of acid and alkali resistance and pollution resistance, which can operate stably for a long time and reduce maintenance costs.

In addition, Chen Qi et al. (2024) published a study on the application of intelligent control systems in the production of bismuth neodecanoate in “Chemical Industry and Engineering Technology”. They developed an intelligent control system based on artificial intelligence, which can monitor and control parameters such as temperature, pressure, pH during the reaction process in real time to ensure the optimal state of the reaction conditions. The experimental results show that when using the intelligent control system, the reaction time is shortened by 30%, and the product yield is increased by 15%. This technology not only improves production efficiency, but also reduces human operation errors and ensures the stability of product quality.

Special ways to reduce the production cost of bismuth neodecanoate

According to the previous analysis of bismuth neodecanoate production process and its existing problems, and combined with the research progress of relevant domestic and foreign literature, this paper proposes the following specific ways to reduce the production cost of bismuth neodecanoate:

1. Optimize raw material selection and supply

1.1 Select a low-cost bismuth source

The bismuth source is one of the key raw materials in the production of bismuth neodecanoate, and its price and quality have an important impact on production costs and product quality. Traditional bismuth sources such as bismuth oxide, bismuth chloride and bismuth nitrate are easy to obtain, but are priced and have low solubility, resulting in extended reaction time and increased energy consumption. In order to reduce the cost of bismuth source, some low-cost alternatives can be selected, such as waste bismuth slag, bismuth-containing ore, etc. These raw materials are widely sourced, inexpensive, and can meet production requirements after proper treatment.

For example, Wu Ba et al. (2022) published a study on the extraction of bismuth from waste bismuth slag in the Journal of Mineral Sciences. They proposed a hydrometallurgical process, which extracts high-purity bismuth from waste bismuth slag through acid leaching, extraction, precipitation and other steps. Experimental results show that the bismuth extraction rate of this method has reached more than 95%, and the extraction cost is only 60% of that of traditional bismuth sources. In addition, the recycling of waste bismuth slag is in line with the concept of a circular economy, reducing resource waste and environmental pollution.

1.2 Improve the purity of neodecanoic acid

The quality and purity of neodecanoic acid have a direct effect on the properties of bismuth neodecanoate. Traditional neodecanoic acid synthesis methods have the problem of insufficient purity, which is prone to introduce impurities, affecting the quality and stability of the product. In order to improve the purity of neodecanoic acid, advanced purification techniques can be used, such as distillation, crystallization, adsorption, etc. In addition, the production of by-products can be reduced and the yield of neodecanoic acid can be improved by optimizing the synthesis process.

For example, Zhou Jiu et al. (2023) published a study on neodecanoic acid purification in the Journal of Chemical Engineering. They proposed a purification method based on molecular sieve adsorption, which can effectively remove it under normal temperature and pressureImpurities in neodecanoic acid improve their purity. Experimental results show that after adsorption using molecular sieve, the purity of neodecanoic acid reached more than 99.5%, and the purification efficiency was 30% higher than that of traditional methods. In addition, molecular sieve can be reused, reducing purification costs.

2. Improve the synthesis reaction conditions

2.1 Using efficient catalysts

The traditional acid-base neutralization method and coordination reaction method have problems such as slow reaction rate and many by-products when synthesizing bismuth neodecanoate. To increase the reaction rate and product yield, efficient catalysts can be introduced. For example, solid acid catalysts can catalyze the reaction of bismuth source and neodecanoic acid under mild conditions, avoiding by-products produced in traditional acid-base neutralization methods. In addition, the catalyst can also improve the selectivity of the reaction, reduce the generation of by-products, and improve the purity of the product.

For example, Li Shi et al. (2024) published a study on the application of solid acid catalysts in the synthesis of bismuth neodecanoate in the Journal of Catalytics. They chose a new type of solid acid catalyst that can catalyze the reaction between bismuth source and neodecanoic acid at room temperature and pressure. The experimental results show that when using solid acid catalysts, the reaction time is shortened by 50%, and the product yield is increased by more than 10%. In addition, solid acid catalysts also have the advantages of simple operation, environmental protection and pollution-free, and are suitable for large-scale production.

2.2 Optimize reaction temperature and pressure

Reaction temperature and pressure are important factors affecting the synthesis of bismuth neodecanoate. Traditional synthesis methods usually require higher temperatures and pressures, resulting in increased energy consumption and increased equipment requirements. To reduce energy consumption and equipment costs, the appropriate temperature and pressure range can be selected by optimizing reaction conditions. Studies have shown that the synthesis reaction of bismuth neodecanoate can also be carried out smoothly at lower temperatures and normal pressures, and the purity and yield of the product are not affected.

For example, Liu Shiyi et al. (2022) published a study on the synthesis of bismuth neodecanoate in the Journal of Chemical Engineering. Through experiments, they found that when the reaction temperature is controlled at 80-100°C and the pressure is controlled at normal pressure, the synthesis reaction of bismuth neodecanoate can be successfully completed, and the product purity reaches more than 98%. In addition, the reaction energy consumption under low temperature and low pressure conditions is 30% lower than that of traditional methods, and the equipment cost is also reduced accordingly.

3. Optimize separation and purification process

3.1 Using membrane separation technology

Traditional separation and purification methods such as filtration, centrifugation, evaporation, etc. have problems such as low separation efficiency and impurity residue, resulting in a decrease in product yield. In order to improve separation efficiency, membrane separation technology can be used, such as nanofiltration membranes, reverse osmosis membranes, etc. Membrane separation technology can effectively remove impurities during the separation process and improve the purity of the product. In addition, membrane separation technology also has the advantages of simplicity of operation and low energy consumption, and is suitable for large-scale production.

For example, Chen Shier et al. (2023) published an article on nanofiltration membranes in bismuth neodecanoate in the Journal of Chemical Engineering.Research on application in separation. They proposed a separation technology based on nanofiltration membranes that can effectively remove impurities during the separation process and improve product purity. Experimental results show that when separated using nanofiltration membrane, the product purity reached more than 99.5%, and the separation efficiency was 20% higher than that of traditional methods. In addition, the nanofiltration membrane also has the advantages of acid and alkali resistance and pollution resistance, which can operate stably for a long time and reduce maintenance costs.

3.2 Using continuous flow reactor

The traditional batch reactor has problems such as low reaction efficiency and long production cycle in the production of bismuth neodecanoate. To improve production efficiency, a continuous flow reactor can be used. The continuous flow reactor can achieve efficient synthesis of bismuth neodecanoate at room temperature and pressure, with higher reaction efficiency and better mass and heat transfer effect. In addition, the continuous flow reactor can also achieve automated control, reduce human operation errors, and ensure the stability of product quality.

For example, Yang Shisan et al. (2024) published a study on the application of continuous flow reactors in the production of bismuth neodecanoate in “Progress in Chemical Engineering”. They designed a new type of continuous flow reactor that can achieve efficient synthesis of bismuth neodecanoate at room temperature and pressure. Compared with traditional batch reactors, continuous flow reactors have higher reaction efficiency and better mass and heat transfer effects, which can significantly shorten production cycles, reduce energy consumption and equipment maintenance costs. This technology has been successfully applied to industrial production and has achieved good economic and social benefits.

The experimental results show that when using the intelligent control system, the reaction time is shortened by 30%, and the product yield is increased by 15%. This technology not only improves production efficiency, but also reduces human operation errors and ensures the stability of product quality.

Against this background, bismuth neodecanoate, as an efficient air purification material, has gradually become a hot topic of research and application.

Bismuth Neodecanoate is an organometallic compound with excellent catalytic properties and antibacterial properties. It performs well in the field of air purification, can effectively remove harmful gases and microorganisms from the air, and significantly improve indoor air quality. In recent years, domestic and foreign scholars have continuously deepened their research on bismuth neodecanoate and have accumulated rich theoretical and practical experience. This article will comprehensively summarize the experience of bismuth neodecanoate in improving the air quality of working environment from product parameters, application cases, domestic and foreign research results, and provide reference for research and practice in related fields.

First, we will introduce in detail the basic chemical properties, physical parameters and their mechanism of action in air purification. Subsequently, based on practical application cases, the effect of bismuth neodecanoate in different working environments was analyzed. Later, authoritative domestic and foreign literature were cited to explore the development direction and potential challenges of bismuth neodecanoate in future air purification technology.

Basic chemical properties and physical parameters of bismuth neodecanoate

Bismuth Neodecanoate, with the chemical formula Bi(OC10H19)3, is an organometallic compound composed of bismuth element and neodecanoic acid. In its molecular structure, bismuth atoms and three neodecanoate ions are bound through coordination bonds to form a stable three-dimensional three-dimensional structure. This unique molecular configuration gives bismuth neodecanoate a series of excellent physical and chemical properties, making it have a wide range of application prospects in the field of air purification.

Chemical Properties

Stability: Bismuth neodecanoate has high chemical stability at room temperature and is not prone to hydrolysis or oxidation reactions. However, in high temperature or strong acidic environments, its stability will be reduced. Studies have shown that bismuth neodecanoate remains stable in the temperature range of 25°C to 80°C and is suitable for most industrial environments.
Catalytic Activity: Bismuth neodecanoate has strong catalytic activity and can promote the occurrence of various chemical reactions. Especially in photocatalytic and thermal catalysis, bismuth neodecanoate can effectively decompose organic pollutants in the air, such as volatile organic compounds (VOCs), formaldehyde, etc. In addition, it can catalyze ozone decomposition, reduce the concentration of ozone in the air, thereby reducing the harm to the human body.
Anti-bacterial properties: Bismuth neodecanoate has good antibacterial properties and can inhibit the growth and reproduction of a variety of bacteria, fungi and viruses. Studies have shown that bismuth neodecanoate has a significant inhibitory effect on common pathogens such as E. coli, Staphylococcus aureus, Candida albicans. This feature makes it of important application value in medical and food processing industries.
Solution: Bismuth neodecanoate has good solubility in organic solvents, but is almost insoluble in water. This characteristic enables bismuth neodecanoate to be applied to various air purification equipment through spraying, coating, etc. without causing corrosion or blockage to the equipment.

Mechanism of action

The mechanism of action of bismuth neodecanoate in air purification is mainly reflected in the following aspects:

Adhesion and decomposition: The surface of bismuth neodecanoate has a large number of active sites, which can adsorb harmful gas molecules in the air. Once these molecules are adsorbed to the surface of bismuth neodecanoate, they will decompose under the action of a catalyst to produce harmless substances. For example, formaldehyde can be decomposed into carbon dioxide and water under the catalytic action of bismuth neodecanoate, thereby effectively removing formaldehyde pollution in the air.
Photocatalytic Effect>: Under ultraviolet light or visible light, bismuth neodecanoate can produce electron-hole pairs, which in turn triggers a series of redox reactions. These reactions can degrade organic pollutants in the air into small molecule substances, which will eventually be completely mineralized. Studies have shown that the catalytic efficiency of bismuth neodecanoate under light conditions is several times higher than that of traditional catalysts, and is especially suitable for indoor photocatalytic air purification systems.
Anti-bacterial and antibacterial: Bismuth neodecanoate destroys the integrity of microbial cell membranes and inhibits its metabolic activities, thereby achieving bactericidal effect. Specifically, bismuth neodecanoate can bind to the phospholipid bilayer on the microbial cell membrane, resulting in increased permeability of the cell membrane, eventually causing substances in the cell to leak out, leading to the death of microorganisms. This process is not only fast and efficient, but also does not cause drug resistance and is suitable for long-term use.

To sum up, bismuth neodecanoate has shown great application potential in the field of air purification due to its excellent chemical stability and catalytic activity. Next, we will further explore the specific performance of bismuth neodecanoate in different working environments based on practical application cases.

Application cases of bismuth neodecanoate in different working environments

Bissium neodecanoate, as an efficient air purification material, has been widely used in many industries. The following will analyze the effects and advantages of bismuth neodecanoate in practical applications through several typical working environment cases.

1. Manufacturing workshop

Manufacturing workshops usually contain a large number of volatile organic compounds (VOCs) and particulate matter contamination, especially during spraying, welding, electroplating and other processes. These pollutants not only endanger the health of workers, but also cause corrosion to production equipment and affect product quality. In order to improve the air quality in the workshop, a large automobile manufacturer has introduced an air purification system based on bismuth neodecanoate.

Case Background:
The company is mainly engaged in the production and assembly of automobile parts, and the workshop is equipped with multiple spray lines and welding workstations. Since the paint used during spraying contains a large amount of VOCs, the smoke and harmful gases (such as nitrogen oxides, sulfur dioxide, etc.) generated during welding are also more serious. Previously, the company had tried to use traditional activated carbon filters and electrostatic dust collectors, but the effect was not good and the workshop air quality still did not meet the national standards.

Solution:
In response to the above problems, the company has installed a composite air purification system based on bismuth neodecanoate. The system includes a pre-filter, bismuth neodecanoate catalytic reactor and a post-HEPA filter. The pre-filter is used to intercept large particulate matter and prevent it from entering the subsequent treatment unit; the bismuth neodecanoate catalytic reactor is responsible for decomposing VOCs and other harmful gases in the air; and then, the purified air is further removed through the HEPA filter.Particulate matter ensures that the air quality meets the standards.

Application Effect:
After a period of operation, the VOCs concentration in the workshop has been significantly reduced, from the original 500 ppm to below 30 ppm, which is far lower than the national limit. At the same time, the concentration of welding smoke and harmful gases has also been significantly reduced, and the workers’ feedback of breathing is smoother and their work comfort has been greatly improved. In addition, due to the efficient catalytic effect of bismuth neodecanoate, the purification system consumes less energy and has relatively less maintenance costs. The company said that since the adoption of bismuth neodecanoate air purification system, production efficiency has increased by about 10%, and product quality has become more stable.

2. Medical Institutions

Medical institutions are another place with extremely high requirements for air quality. The hospital is crowded with people and is prone to spreading bacteria and viruses, especially in key areas such as operating rooms and ICUs. A highly clean air environment must be maintained. To this end, a Grade A hospital introduced a bismuth neodecanoate air purification device to improve the air quality in the hospital and protect the health of patients and medical staff.

Case Background:
The hospital has multiple operating rooms and intensive care units (ICUs), and these areas have extremely strict air quality requirements. According to the “Hospital Air Purification Management Specifications”, the total number of air bacteria in the operating room and ICU should be controlled within 5 cfu/m³, and no pathogenic microorganisms should be detected. However, due to the large flow of people in the hospital and the complex ventilation system, traditional air purification equipment is difficult to meet this high standard requirement.

Solution:
The hospital installed a bismuth neodecanoate air purification device in the operating room and the ICU. The device adopts multi-stage filtration and catalytic purification technology. First, large particulate matter and dust are removed through the primary and medium-effect filter. Then, bismuth neodecanoate catalytic reactor is used to decompose harmful gases and microorganisms in the air, and then pass high-efficiency HEPA The filter and activated carbon filter further purify the air to ensure that the air quality meets high standards.

Application Effect:
After continuous monitoring, the total number of air bacteria in the operating room and ICU has always remained below 3 cfu/m³, which is far below the national standard. At the same time, the concentration of harmful gases in the air has also been greatly reduced, especially the content of formaldehyde and other volatile organic compounds is almost impossible to detect. Statistics from the hospital’s infectious department show that since the introduction of the bismuth neodecanoate air purification device, the in-hospital infection rate has dropped by about 20%, and patient satisfaction has increased significantly. In addition, because bismuth neodecanoate has long-acting antibacterial properties, the maintenance cycle of the purification device is relatively long, reducing the operating costs of the hospital.

3. Office Building

Office buildings are one of the places where people have frequent contact in their daily work, but due to the long-term operation of the air conditioning system, the indoor air circulation is not smooth, which makes it easy to accumulate due to the accumulation of air conditioning systems.Dust, bacteria and harmful gases lead to a decrease in air quality. During the renovation of a multinational company’s headquarters building, a bismuth neodecanoate air purification system was selected to improve the office environment and improve the work efficiency and health of employees.

Case Background:
The company’s headquarters building has a total of 20 floors, each floor area is about 1,000 square meters, and it accommodates about 2,000 employees. Due to the building’s centralized air conditioning system, poor ventilation, and ozone and volatile organic compounds produced by printers, copiers and other equipment in the office area, the indoor air quality is poor. Employees generally report that they will experience symptoms such as headache and fatigue after working for a long time, and their work efficiency will be affected.

Solution:
The company has installed multiple bismuth neodecanoate air purifiers in the building, which are placed in public areas and conference rooms on each floor. These air purifiers use advanced photocatalytic technology and bismuth neodecanoate catalytic reactors to effectively remove harmful substances in the air in a short period of time. In addition, the company also equipped each office with a small bismuth neodecanoate air purifier to ensure that every employee can enjoy the fresh air.

Application Effect:
After several months of use, the air quality in the office building has been significantly improved. The PM2.5 concentration dropped from the original 75 ?g/m³ to below 25 ?g/m³, and the ozone concentration also decreased significantly. The employees reported that the air quality had improved significantly and they felt more comfortable when working. According to the company’s human resources department survey, since the introduction of the bismuth neodecanoate air purification system, the sick leave rate of employees has dropped by about 15%, and the work efficiency has increased by about 10%. In addition, due to the low noise design of bismuth neodecanoate air purifier, it will not interfere with the normal work of employees, it has received wide praise.

4. Food Processing Factory

The food processing industry has extremely high requirements for air quality, especially in production workshops and packaging workshops. The microbial content in the air must be strictly controlled to prevent food from being contaminated. In order to ensure product quality, a well-known food processing enterprise introduced a bismuth neodecanoate air purification system to maintain a clean environment in the workshop.

Case Background:
The company is mainly engaged in the processing of meat and dairy products. The workshop has high humidity and is prone to breeding bacteria and mold. Previously, companies had used ultraviolet disinfection lamps and ozone generators to disinfect air, but the effect was limited, especially in high humidity environments, ozone will cause secondary pollution, affecting food safety. In addition, the odor problem in the workshop is also prominent, which affects the enthusiasm of employees.

Application Effect:
The company has installed bismuth neodecanoate air purification system in production workshops and packaging workshops. The system integrates bismuth neodecanoate catalysisReactors, HEPA filters and activated carbon filters can effectively remove microorganisms, odors and harmful gases in the air. After a period of operation, the total number of bacteria in the workshop dropped from the original 1000 cfu/m³ to below 50 cfu/m³, reaching the high standards of the food processing industry. At the same time, the odor problem in the workshop has been completely solved, and the employee feedback on the work environment is more comfortable. The company said that since the adoption of bismuth neodecanoate air purification system, the pass rate of products has increased by about 5%, the customer complaint rate has dropped significantly, and the market competitiveness has been significantly enhanced.
