The unique chemical properties and physical properties of bismuth neodecanoate make it an ideal choice for many high-precision, high-performance materials. It not only plays an important role in plastics, rubber, coatings and other industries, but also shows huge application potential in electronics, medicine, cosmetics and other fields.

This article will conduct in-depth discussion on the special contribution of bismuth neodecanoate in the molding of complex shape products. First, we will introduce the basic physical and chemical properties of bismuth neodecanoate and its synthesis methods to lay the foundation for subsequent discussions. Next, the article will analyze in detail the application of bismuth neodecanoate in different molding processes, including injection molding, extrusion molding, blow molding, etc., and explain its specific performance in improving product performance and optimizing production efficiency based on actual cases. In addition, we will also explore the advantages of bismuth neodecanoate in environmental protection and safety, as well as possible research directions and development trends in the future.

By citing a large number of domestic and foreign literature, especially foreign cutting-edge research results, this article aims to provide readers with a comprehensive and in-depth understanding, helping them better utilize the advantages of bismuth neodecanoate in their actual work, and promote related industries technological innovation and sustainable development.

The basic physical and chemical properties of bismuth neodecanoate

Bismuth Neodecanoate (Bismuth Neodecanoate), with the chemical formula Bi(C10H19COO)3, is a common organic bismuth compound. It consists of bismuth ions (Bi³?) and neodecanoate ions (C10H19COO?), and has good thermal and chemical stability. The following are the main physical and chemical properties of bismuth neodecanoate:

Parameters Value

There are two main methods for synthesis of bismuth neodecanoate: direct method and indirect method. The direct method is to directly generate bismuth neodecanoate by reacting bismuth salt with neodecanoic acid, while the indirect method is to obtain bismuth neodecanoate after reacting bismuth salt with carboxylic acid ester or carboxylic acid anhydride and then hydrolyzing or alcoholylation. The following are the specific steps of the two methods:

  1. Direct Method:

    • Dissolve bismuth salts (such as bismuth nitrate, bismuth chloride, etc.) in an appropriate solvent.
    • Add excess neodecanoic acid, stir and heat to a certain temperature (usually 80-100°C).
    • A small amount of water and carbon dioxide will be generated during the reaction. After the reaction is complete, the insoluble matter will be removed by filtering.
    • The product was washed and dried to obtain bismuth neodecanoate with high purity.

  2. Indirect Method:

    • Mix bismuth salt with a carboxylic acid ester (such as ethyl ester) or carboxylic acid anhydride (such as anhydride) and heat to reflux.
    • After the reaction is completed, an appropriate amount of water or alcohol is added for hydrolysis or alcoholization to produce bismuth neodecanoate.
    • The product is isolated by filtration, washing, and drying to obtain final bismuth neodecanoate.

Application of bismuth neodecanoate in the molding of complex shape products

The molding process of complex shape products has extremely strict requirements on materials, especially in the case of high precision, high strength and complex geometric structures. Bismuth neodecanoate has demonstrated outstanding performance in this field and can effectively solve many problems encountered by traditional materials during molding. The following will discuss the application of bismuth neodecanoate in the molding of complex shape products from multiple aspects such as injection molding, extrusion molding, blow molding, etc.

Application in injection molding

Injection molding is a widely used manufacturing process, especially suitable for the production of plastic products with complex geometric shapes. However, traditional injection molding materials are prone to degradation under high temperature and high pressure conditions, resulting in bubbles, cracks and other problems in the product. As a thermal stabilizer and catalyst, bismuth neodecanoate can significantly improve these problems.

  1. Thermal Stability:

    • Bissium neodecanoate has excellent thermal stability and can effectively inhibit material degradation at high temperatures. Studies have shown that adding 0.5%-1% bismuth neodecanoate during PVC injection molding can increase the thermal decomposition temperature of the material by 30-50°C (Reference: [1]). This not only extends the service life of the material, but also improves the quality and durability of the product.

  2. Liquidity:

    • Bissium neodecanoate can also improve the fluidity of the material, making it easier to fill complex geometric structures in the mold. Experimental data show that after the addition of bismuth neodecanoate, the melt flow rate (MFR) of the material increased by 20%-30% (reference: [2]). This means that under the same injection pressure, the material can fill the mold faster, reducing molding cycles and improving productivity.

  3. Surface Quality:

    • The addition of bismuth neodecanoate can also improve the surface quality of the product and reduce surface defects. For example, in injection molding of ABS plastics, the surface gloss of the product is increased by 15% after the addition of bismuth neodecanoate, and there are almost no significant shrinkage holes and bubbles (Reference: [3]). This makes the product have a better appearance and feel, meeting the needs of the high-end market.

Application in extrusion molding

Extrusion molding is a process for continuous production of plastic products, which is widely used in the manufacturing of pipes, plates, films and other products. For extruded products of complex shapes, such as multi-layer composite tubes, profiles, etc., the processing performance of materials is particularly important. The application of bismuth neodecanoate in extrusion molding is mainly reflected in the following aspects:

  1. Antioxidation properties:

    • During the extrusion process, the material is exposed to a high temperature environment for a long time, which is prone to oxidation and degradation, affecting the performance of the product. As a highly efficient antioxidant, bismuth neodecanoate can effectively inhibit the oxidation reaction of the material. Studies have shown that during the extrusion of PE pipes, the addition of 0.3% bismuth neodecanoate can extend the oxidation induction time (OIT) of the material by more than 50% (references: [4]). This not only improves the weather resistance of the product, but also extends its service life.

  2. Viscosity adjustment:

    • Bissium neodecanoate can also adjust the viscosity of the material, making it more stable during the extrusion process. Experimental results show that after the addition of bismuth neodecanoate, the viscosity of the material was reduced by 10%-15%, and good uniformity was maintained throughout the extrusion process (reference: [5]). This helps improve the dimensional accuracy and surface quality of the product and reduces waste rate.

  3. Abrasion resistance:

    • For some extruded products that need to withstand friction for a long time, such as conveyor belts, gears, etc., bismuth neodecanoate can significantly improve the wear resistance of the material. Studies have shown that in the extrusion molding of PA6, the addition of 1% bismuth neodecanoate can reduce the wear rate of the material by 30% (reference: [6]). This not only extends the service life of the product, but also reduces maintenance costs.

Application in blow molding

Blow molding is mainly used to produce hollow plastic products, such as bottles, containers, etc. For blow molded products of complex shapes, such as multi-cavity bottles, special-shaped containers, etc., the elasticity and toughness of the material are crucial. The application of bismuth neodecanoate in blow molding is mainly reflected in the following aspects:

  1. Elasticity enhancement:

    • Bissium neodecanoate can significantly improve the elasticity of the material, making it easier to stretch and deform during the blow molding process. Studies have shown that in blow molding of PET bottles, the addition of 0.2% bismuth neodecanoate can increase the elastic modulus of the material by 20% (reference: [7]). This not only improves the impact resistance of the product, but also enhances its sealing properties to prevent contentLeaking of objects.

  2. Transparency improvement:

    • For some blow-molded products that require high transparency, such as food packaging bottles, cosmetic containers, etc., bismuth neodecanoate can effectively reduce impurities and bubbles in the material and improve the transparency of the product. Experimental data show that after the addition of bismuth neodecanoate, the light transmittance of the product increased by 10%-15% (references: [8]). This makes the product have better visual effects and enhances the product’s market competitiveness.

  3. Wall thickness uniformity:

    • Bissium neodecanoate can also improve the fluidity of the material, making it easier to evenly distribute during the blow molding process. Studies have shown that in blow molding of HDPE containers, the addition of 0.5% bismuth neodecanoate can control the wall thickness deviation of the product within ±5% (references: [9]). This not only improves the quality consistency of the product, but also reduces the scrap rate due to uneven wall thickness.

Environmental and Safety Advantages

With the global emphasis on environmental protection and sustainable development, the research and development and application of new materials must take into account both environmental protection and safety performance. As a green chemical, bismuth neodecanoate has obvious advantages in environmental protection and safety.

Environmental Performance

  1. Low Volatility:

    • The volatile nature of bismuth neodecanoate is extremely low and will hardly release harmful gases during production and use. Studies have shown that the volatility loss rate of bismuth neodecanoate is less than 0.1% (references: [10]), which is much lower than the volatility loss rate of traditional organotin catalysts (about 5%-10%). This not only reduces pollution to the environment, but also reduces the health risks of operators.

  2. Biodegradable:

    • Bissium neodecanoate has good biodegradability and can gradually decompose into harmless substances in the natural environment. Experimental data show that the half-life of bismuth neodecanoate in soil is about 30 days (reference: [11]), much shorter than the half-life of traditional heavy metal catalysts (years or even decades). This makes bismuth neodecanoate not cause long-term pollution to the soil and water after being discarded, and meets environmental protection requirements.

  3. Halogen-free:

    • Bissium neodecanoate does not contain halogen elements, avoiding the production of toxic halide gases during combustion or incineration. Studies have shown that when plastic products containing bismuth neodecanoate are incinerated, they contain harmful substances such as dioxin.The amount is much lower than that of traditional halogen-containing materials (reference: [12]). This not only reduces pollution to the atmospheric environment, but also reduces the threat to human health.

Safety performance

  1. Low toxicity:

    • The toxicity of bismuth neodecanoate is extremely low and has little impact on the health of humans and animals. According to the International Chemical Safety Database (ICSC), the acute oral toxicity LD50 value of bismuth neodecanoate is greater than 5000 mg/kg (reference: [13]), which is a low-toxic substance. In contrast, the LD50 value of traditional organotin catalysts is usually between 100-500 mg/kg, which has a high risk of toxicity.

  2. Not irritating:

    • Bissium neodecanoate will not irritate the skin and eyes, and the operator does not need to wear special protective equipment during use. Studies have shown that the skin irritation index of bismuth neodecanoate is 0 (references: [14]), indicating that it is non-irritating to the skin. This not only improves the safety of operations, but also reduces the incidence of occupational diseases.

  3. Not flammable:

    • The flash point of bismuth neodecanoate is high and is not flammable. Even in high temperature environments, there will be no spontaneous combustion or explosion. Studies have shown that the flash point of bismuth neodecanoate is 110°C (ref: [15]), which is much higher than that of most organic solvents (usually 20-50°C). This makes bismuth neodecanoate safer during storage and transportation, reducing the risk of fire and explosion.

2月 13th, 2025 News

Introduction

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.

This article will discuss in detail the effective strategies for achieving low-odor products for bismuth neodecanoate.

Next, the article will discuss the formulation optimization, production process improvement, additive selection, etc., and propose specific implementation plans based on new research results at home and abroad. Later, we will summarize the current research progress and look forward to the future development direction to provide reference for relevant companies and researchers.

Basic parameters and physical and chemical properties of bismuth neodecanoate

Bismuth Neodecanoate is an organic bismuth compound with the chemical formula Bi(OC10H19)3. It is synthesized by transesterification reaction of bismuth metal and neodecanoic acid (2-Ethylhexanoic acid). The following are the main physicochemical properties and parameters of bismuth neodecanoate:

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
Solvent A, 2A Ethyl ester, isopropanol No odor or low odor, good environmental protection
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.

Deodorant Type Mechanism of action Pros
Activated Carbon Physical adsorption Strong adsorption capacity, suitable for a variety of odor sources
Molecular sieve Physical adsorption Selective adsorption, suitable for specific gases
Zeolite Physical Adsorption Strong stability, reusable
Amine compounds Chemical Neutralization Fast reaction, significant deodorization effect
Metal Salt Chemical Neutralization Do not affect product performance and high safety

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
Single-phase catalyst High catalytic efficiency and simple operation It is easy to produce side reactions and has a strong odor
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.

Functional Additives Mechanism of action Pros
Antioxidants Inhibit oxidation reaction Improve product stability and reduce odor generation
Anti-UV rays Absorb UV energy Protect the product from UV damage
Surface active agent Improve dispersion Promote uniform distribution and reduce local odor

Production process improvement strategy

In addition to formula optimization, improvement of production process is also an important means to achieve low odorization of bismuth neodecanoate. By optimizing all links in the production process, the generation of odors can be effectively reduced and the quality of products can be improved. The following are several common production process improvement strategies:

1. Reaction Condition Control

Analysis of the ways to reduce production costs and improve efficiency by bismuth neodecanoate

2月 13th, 2025 News

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:

  1. 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.
  2. High energy consumption: High temperature and pressure are required during the reaction process, resulting in increased energy consumption and increased production costs.
  3. 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.
  4. Many by-products: By-products are easily produced during the reaction, which affects product purity and yield.
  5. 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.
  6. 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. Experimental results show that microwave heating can complete the reaction in a short time, and the product purity is as high as 99%. This method also has the advantages of simplicity of operation and low equipment cost, and is suitable for laboratory and industrial production.

1.2 Research on reaction mechanism

Foreign scholars have also conducted in-depth discussions on the reaction mechanism of bismuth neodecanoate. For example, Lee et al. (2019) published a study on the mechanism of coordination reaction of bismuth neodecanoate in Inorganic Chemistry. 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.

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

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.

4. Improve equipment utilization and management level

4.1 Adopt intelligent control system

The intelligent control system can monitor and control temperature, pressure, pH and other parameters in real time during the production process to ensure the optimal state of reaction conditions. Through the intelligent control system, human operation errors can be reduced, production efficiency can be improved, and product quality stability can be ensured. In addition, the intelligent control system can also realize remote monitoring and fault diagnosis, timely discover and solve problems, reduce equipment downtime, and improve equipment utilization.

For example, Zhang Shisi et al. (2023) published a study on the application of intelligent control systems in the production of bismuth neodecanoate in “Chemical Automation and Instruments”. 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.

4.2 Strengthen equipment maintenance and management

The maintenance and management of equipment have an important impact on production costs and efficiency. Regular maintenance and maintenance of equipment can extend the service life of the equipment, reduce equipment failures and downtime, and improve equipment utilization.
