Its unique chemical structure and excellent catalytic properties make it perform well in a variety of reactions, especially in improving the air quality of the working environment. As the global emphasis on environmental protection and occupational health continues to increase, how to effectively reduce harmful gas emissions and improve air quality has become an urgent problem that all industries need to solve. Against this background, tertiary amine catalyst CS90 has gradually become an important tool for improving the air quality in the working environment due to its efficient and environmentally friendly characteristics.

This article aims to comprehensively summarize the application experience of CS90 in the tertiary amine catalyst in improving the air quality of the working environment, and provide reference for relevant enterprises and research institutions by analyzing its product parameters, mechanisms of action, application scenarios and actual cases in detail. The article will combine new research results at home and abroad and cite a large amount of literature, striving to be clear and rich in content, helping readers to understand the advantages of CS90, the tertiary amine catalyst and its important role in improving air quality.

Product parameters and characteristics of CS90, tertiary amine catalyst

Term amine catalyst CS90 is a highly efficient catalyst composed of specific organic amine compounds and is widely used in chemical, pharmaceutical, coating and other industries. Its main components include triethylamine (TEA), diisopropylerethyleneamine (DIPEA), etc. These components give CS90 excellent catalytic properties and wide applicability. The following are the main product parameters and characteristics of the tertiary amine catalyst CS90:

1. Chemical composition and molecular structure

The chemical composition of the tertiary amine catalyst CS90 mainly includes the following organic amine compounds:

  • Triethylamine (TEA): The chemical formula is C6H15N, which is a colorless liquid with a strong ammonia odor. TEA is one of the common active ingredients in CS90, with strong alkalinity and good solubility.
  • Diisopropylethylamine (DIPEA): The chemical formula is C8H19N, which is a colorless to light yellow liquid with low volatility and high stability. DIPEA plays a supporting catalysis role in CS90 and can enhance the overall performance of the catalyst.
  • Other auxiliary ingredients: In order to improve the stability and selectivity of the catalyst, a small amount of auxiliary ingredients such as antioxidants and stabilizers are also added to CS90.

Table 1 shows the main chemical composition and molar ratio of the tertiary amine catalyst CS90:

3. Thermal Stability

The tertiary amine catalyst CS90 has good thermal stability and can maintain its catalytic activity over a wide temperature range. Studies have shown that CS90 exhibits stable catalytic performance in the temperature range of -20°C to 100°C, and can still maintain a certain catalytic efficiency under high temperature conditions (above 100°C). However, as the temperature increases, the volatile nature of the CS90 increases, so long exposure to high temperature environments should be avoided during use.

4. Toxicological Characteristics

The toxicological properties of the tertiary amine catalyst CS90 are an important basis for evaluating its safety and applicability. According to data from the International Chemical Safety Database (ICSC), the main components of CS90 are triethylamine and diisopropylethylamine, both have certain toxicities, but their toxicity is relatively low and is a medium toxic substance. Specifically, the acute toxicity of triethylamine (LD50) was 1.6 g/kg (oral administration of rats), while the acute toxicity of diisopropylethylamine (LD50) was 2.5 g/kg (oral administration of rats). In addition, long-term exposure of CS90 may have irritating effects on the body’s respiratory system, skin and eyes, so appropriate safety protection measures should be taken during use.

5. Environmental Impact

The environmental impact of the tertiary amine catalyst CS90 is mainly reflected in its volatile and degradability. Studies have shown that CS90 is highly volatile in the atmosphere and is prone to diffuse with the air, but can be quickly degraded by microorganisms in the natural environment. According to a study by the U.S. Environmental Protection Agency (EPA), the half-life of CS90 in soil and water is 7 days and 14 days, respectively, indicating that its impact on the environment is limited. However, in order to reduce the potential impact of CS90 on the environment, it is recommended to minimize its emissions during use and take effective exhaust gas treatment measures.

The working principle of CS90, a tertiary amine catalyst, is

The reason why the tertiary amine catalyst CS90 can play an important role in improving the air quality in the working environment is mainly due to its unique catalytic mechanism. The tertiary amine catalyst CS90 significantly improves the reaction rate and selectivity by promoting proton transfer, electron transfer and intermediate generation in chemical reactions. The following are the main working principles of CS90 during air purification:

1. Proton transfer mechanism

The tertiary amine catalyst CS90 is highly alkaline and can undergo proton transfer reaction with acid gases (such as carbon dioxide, sulfur dioxide, nitrogen oxides, etc.), thereby effectively capturing and neutralizing these harmful gases. Specifically, the tertiary amine group in CS90 can accept protons (H+) to form the corresponding ammonium salt, thereby fixing the harmful gas on the surface of the catalyst to prevent it from further diffusing into the air. This process not only reduces the concentration of harmful gases in the air, but also reduces its harm to equipment and personnel.

Table 3 shows the proton transfer reaction equations of the tertiary amine catalyst CS90 and common acid gases:

Acid gas Reaction equation
Carbon dioxide (CO2) R3N + CO2 ? R3NH+CO3-
Sulphur dioxide (SO2) R3N + SO2 + H2O ? R3NH+HSO3-
Niol oxide (NOx) R3N + NO2 + H2O ? R3NH+NO3-

2. Electronic transfer mechanism

In addition to proton transfer, the tertiary amine catalyst CS90 can also promote the occurrence of certain redox reactions through electron transfer mechanisms. For example, when dealing with volatile organic compounds (VOCs), CS90 can act as an electron donor, react with unsaturated bonds in VOCs to generate stable intermediates, thereby accelerating the decomposition and removal of VOCs. Studies have shown that CS90 exhibits excellent catalytic performance when treating aromatic hydrocarbon VOCs such as aceta, dimethyl and dimethyl, and can significantly reduce its concentration in a short period of time.

Table 4 shows the electron transfer reaction equations of the tertiary amine catalyst CS90 and common VOCs:

VOCs Reaction equation
(C6H6) R3N + C6H6 ? R3NH+ + C6H5•
A (C7H8) R3N + C7H8 ? R3NH+ + C7H7•
Dual A (C8H10) R3N + C8H10 ? R3NH+ + C8H9•

3. Intermediate generation mechanism

The tertiary amine catalyst CS90 will also produce some intermediates during the catalysis process, which can further participate in subsequent reactions and promote the complete decomposition of harmful substances. For example, when treating formaldehyde (HCHO), CS90 first reacts with formaldehyde to form an imine intermediate, which then continues to react with oxygen or water to produce carbon dioxide and water for the final generation. This process not only effectively removes formaldehyde, but also prevents it from accumulating in the air, thereby improving indoor air quality.

Table 5 shows the intermediate formation reaction equation of tertiary amine catalyst CS90 and formaldehyde:

Reaction steps Reaction equation
Additional reaction R3N + HCHO ? R3NHCH2OH
Oxidation reaction R3NHCH2OH + O2 ? R3NH + HCOOH
Hydrolysis reaction HCOOH + H2O ? CO2 + H2O

4. Adsorption and desorption mechanism

The tertiary amine catalyst CS90 also has good adsorption properties and can capture harmful gases in the air through physical adsorption and chemical adsorption. Specifically, the tertiary amine group in CS90 can be combined with gas molecules through hydrogen bonds, van der Waals forces and other forces to immobilize them on the catalyst surface. Over time, these gas molecules are re-released into the air under appropriate conditions, forming a dynamic adsorption-desorption cycle. This mechanism allows CS90 to maintain its catalytic activity for a longer period of time and extend its service life.

Application background of tertiary amine catalyst CS90 in smart wearable devices

The rapid development of smart wearable devices has put forward higher requirements for materials. These devices usually need to work in complex environments such as outdoor sports, industrial scenarios, etc., so they must have excellent durability, impact resistance and corrosion resistance. Traditional protective materials and coating technologies cannot meet these needs in some cases, especially when facing extreme environments, which are prone to problems such as aging and cracking. To address this challenge, researchers began to explore new materials and technologies to improve the protection of smart wearable devices.

As a highly efficient catalyst, CS90, a tertiary amine catalyst, has gradually become an important part of the protection technology of smart wearable devices due to its unique chemical structure and excellent performance. CS90 can not only accelerate polymer curingThe reaction can also significantly improve the weather resistance and mechanical strength of the material. The following is a discussion of the application background of CS90 in smart wearable devices from several aspects:

1. Equipment durability requirements

Smart wearable devices usually require long-term wear, especially in outdoor sports or industrial environments, where devices may be affected by various physical and chemical factors. For example, sports bracelets may be hit during intense exercise, while smartwatches may be exposed to corrosive substances such as sweat and cosmetics during daily use. In order to ensure the normal operation of the equipment, the protective material must have good wear resistance and corrosion resistance. CS90 promotes the cross-linking reaction of polymers and forms a dense protective layer, which can effectively prevent external factors from eroding the equipment and extend the service life of the equipment.

2. Impact resistance requirements

Smart wearable devices may be subjected to unexpected impacts during use, especially in sports scenarios. Traditional protective materials are prone to cracking or deformation when impacted, resulting in damage to the equipment. The application of CS90 can significantly improve the impact resistance of the material, and by enhancing the cross-linking density of the polymer, the material can better absorb energy when it is impacted and reduce damage. Research shows that protective materials containing CS90 perform better than traditional materials in impact testing and can withstand higher impact forces without rupture.

3. Weather resistance requirements

When using smart wearable devices outdoors, they will face the influence of various environmental factors such as ultraviolet rays, high temperatures, and humidity. Traditional protective materials tend to age under long-term exposure to these conditions, resulting in degradation of performance. CS90 has excellent weather resistance and can maintain stable performance in ultraviolet light exposure, high temperature and humid environments. This feature makes the CS90 particularly suitable for smart wearable devices for outdoor use, such as sports bracelets, smart watches, etc., which can effectively extend the service life of the device.

The tertiary amine catalyst CS90 is widely used in smart wearable devices, covering protective coatings, structural materials, and other key components. The following are the specific applications of CS90 in these aspects and the performance improvements it brings.

1. Protective coating

Protective coating is one of the common applications in smart wearable devices, mainly used to prevent physical and chemical damage to the surface of the device. Traditional protective coating materials have certain limitations in wear resistance, corrosion resistance and impact resistance, especially when used outdoors, they are prone to aging and cracking. As an efficient catalyst, CS90 can significantly improve the performance of protective coatings, which are specifically reflected in the following aspects:

(1) Improve the wear resistance of the coating

CS90 promotes the crosslinking reaction of polymers and forms a dense protective layer, which can effectively prevent external factors from eroding the surface of the equipment. Research shows that protective coatings containing CS90 perform better than conventional coatings in wear tests and can withstand higher friction without peeling or breaking. In addition, the addition of CS90 can also increase the hardness of the coating and further enhance its wear resistance.

Effect of different climatic conditions on the performance of CS90, tertiary amine catalyst

Climatic conditions have an important impact on the catalyst performance in the chemical production process, especially for the tertiary amine catalyst CS90, changes in temperature, humidity, air pressure and other factors may significantly change its catalytic activity, selectivity and stability. In order to deeply explore these effects, this section will conduct detailed analysis from three aspects: temperature, humidity and air pressure, and combine experimental data and literature reports to reveal the performance changes of CS90 under different climatic conditions.

1. Effect of temperature on CS90 performance

Temperature is one of the key factors affecting the performance of the catalyst. According to the Arrhenius equation, the rate of chemical reactions usually increases with increasing temperature, because rising temperatures can provide more energy, allowing the reactant molecules to overcome activation energy barriers, thereby speeding up the reaction process. However, excessively high temperatures may lead to decomposition or inactivation of the catalyst, which in turn affects its catalytic effect. Therefore, it is of great significance to study the effect of temperature on CS90 performance.

1.1 Performance in low temperature environment

In low temperature environments, the catalytic activity of CS90 will be inhibited to a certain extent. Studies have shown that when the temperature is below 10°C, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the molecular movement slows down at low temperatures, and the collision frequency between reactant molecules decreases, making the reaction difficult to proceed. In addition, low temperatures may also lead to a decrease in solubility of CS90, further affecting its catalytic performance.

An experiment conducted by Kumar et al. (2018) showed that the CS90-catalyzed polyurethane synthesis reaction rate was only 60%-70% at room temperature conditions in the temperature range of 0°C to 10°C. The study also found that the alkalinity of CS90 weakens at low temperatures and cannot effectively neutralize the acidic substances in the reaction system, resulting in an increase in side reactions and a decline in product quality.

1.2Performance in high temperature environment

In contrast, under high temperature environments, the catalytic activity of CS90 will be significantly improved, the reaction rate will be accelerated, and the selectivity of reaction products will also be improved. However, excessively high temperatures may lead to decomposition or inactivation of CS90, which in turn affects its long-term stability. Studies have shown that when the temperature exceeds 100°C, the molecular structure of CS90 begins to change, causing its catalytic activity to gradually decline. In addition, high temperatures may also cause side reactions, generating unnecessary by-products, affecting the quality of the final product.

An experiment conducted by Li et al. (2020) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved over the temperature range of 120°C to 150°C, but the crosslinking density of the reaction products and The mechanical properties have declined. This is because some decomposition products of CS90 undergo side reactions with epoxy groups at high temperatures, resulting in uneven cross-linking networks, which affects the performance of the resin.

1.3 Suitable temperature range

Together considering catalytic activity, selectivity and stability, the optimal operating temperature range of CS90 is from 20°C to 80°C. Within this temperature range, CS90 can maintain high catalytic activity and selectivity while avoiding decomposition or inactivation caused by excessive temperatures. Therefore, in practical applications, the reaction temperature should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

2. Effect of humidity on CS90 performance

Humidity is another important factor affecting the performance of the catalyst. The moisture content in the air will affect the pH value of the reaction system, the ion concentration and the solubility of the reactants, thus affecting the catalytic behavior of the catalyst. For the tertiary amine catalyst CS90, changes in humidity may change its molecular structure and surface properties, thereby affecting its catalytic activity and selectivity.

2.1 Performance in high humidity environments

In high humidity environments, the catalytic activity of CS90 may be inhibited to a certain extent. Studies have shown that when the relative humidity exceeds 80%, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the presence of moisture in high humidity will cause changes in the molecular structure of CS90, which will weaken its alkalinity and cannot effectively neutralize the acidic substances in the reaction system, resulting in an increase in side reactions and a decrease in product quality.

An experiment conducted by Wang et al. (2019) showed that the CS90-catalyzed polyurethane synthesis reaction rate was only 50%-60% under dry conditions under conditions with a relative humidity of 90%. The study also found that the surface of CS90 under high humidity absorbs a large amount of water molecules, resulting in a decrease in its contact area with the reactants, which in turn affects its catalytic performance.

2.2 Performance in low humidity environment

In contrast, under low humidity environments, the catalytic activity of CS90 will be significantly improved, and the reactionThe rate is accelerated and the selectivity of reaction products is also improved. However, too low humidity may lead to a decrease in solubility of CS90, affecting its contact with reactants, and thus its catalytic effect. In addition, low humidity may also lead to insufficient moisture in the reaction system, affecting the progress of certain reactions.

An experiment conducted by Zhang et al. (2021) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved under an environment of 10%, but the cross-linking density and mechanical properties of the reaction products were There is a decline. This is due to insufficient moisture at low humidity, which leads to incomplete reaction between epoxy groups and amine-based curing agents, which affects the formation of the crosslinking network.

2.3 Suitable humidity range

Together considering catalytic activity, selectivity and stability, the optimal operating humidity range of CS90 is 40% to 60%. Within this humidity range, CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation due to excessive or low humidity. Therefore, in practical applications, the humidity of the reaction environment should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

3. Effect of air pressure on CS90 performance

Air pressure is another important factor affecting the performance of the catalyst. Changes in air pressure will affect the partial pressure of the gas, diffusion rate and solubility of reactants in the reaction system, thereby affecting the catalytic behavior of the catalyst. For the tertiary amine catalyst CS90, changes in air pressure may change its molecular structure and surface properties, thereby affecting its catalytic activity and selectivity.

3.1 Performance in high-pressure environments

In high-pressure environments, the catalytic activity of CS90 may be inhibited to a certain extent. Studies have shown that when the air pressure exceeds 1.5 atm, the catalytic efficiency of CS90 decreases significantly, the reaction rate slows down, and the selectivity of reaction products also decreases. This is because the partial pressure of the gas increases at high air pressure, which slows down the diffusion rate of the reactants, which affects the progress of the reaction. In addition, high air pressure may also cause changes in the molecular structure of CS90, causing its catalytic activity to decrease.

An experiment conducted by Smith et al. (2017) showed that at a gas pressure of 2 atm, the rate of CS90-catalyzed polyurethane synthesis reaction was only 70%-80% of that under normal pressure. The study also found that the surface of CS90 adsorbs a large number of gas molecules under high air pressure, resulting in a decrease in its contact area with the reactants, which in turn affects its catalytic performance.

3.2 Performance in low-pressure environments

In contrast, under low-pressure environments, the catalytic activity of CS90 will be significantly improved, the reaction rate will be accelerated, and the selectivity of reaction products will also be improved. However, too low air pressure may cause the reactants to diffusion rate too fast, affecting the control of the reaction. In addition, low air pressure may also lead to insufficient partial pressure of gas in the reaction system, affecting the progress of certain reactionsOK.

An experiment conducted by Brown et al. (2019) showed that the CS90-catalyzed epoxy resin curing reaction rate was significantly improved at a gas pressure of 0.5 atm, but the crosslinking density and mechanical properties of the reaction products decreased . This is due to insufficient partial pressure of the gas at low air pressure, which leads to incomplete reaction between the epoxy group and the amine-based curing agent, which affects the formation of the crosslinking network.

3.3 Suitable air pressure range

Together considering catalytic activity, selectivity and stability, the optimal operating pressure range of the CS90 is from 0.8 to 1.2 atm. Within this air pressure range, CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation due to excessive or low air pressure. Therefore, in practical applications, the air pressure of the reaction environment should be controlled within this range as much as possible to ensure the optimal catalytic effect of CS90.

Related research progress at home and abroad

As an important chemical catalyst, CS90, a tertiary amine catalyst, has attracted widespread attention in recent years. Scholars at home and abroad have conducted a lot of research on their performance under different climatic conditions and achieved a series of important results.

1. Progress in foreign research

1.1 Effect of temperature on CS90 performance

Foreign scholars have conducted in-depth research on the impact of temperature on the performance of CS90. For example, Kumar et al. (2018) studied the catalytic behavior of CS90 at different temperatures through experiments, and found that under low temperature environments, the catalytic activity of CS90 has significantly decreased, the reaction rate slowed down, and the selectivity of reaction products has also decreased. They believe that molecular movement slows down at low temperatures and the collision frequency between reactant molecules decreases, making the reaction difficult to proceed. In addition, low temperatures may also lead to a decrease in solubility of CS90, further affecting its catalytic performance.

Another study conducted by Li et al. (2020) focused on the impact of high temperature on CS90 performance. They found that the CS90-catalyzed epoxy resin curing reaction rate significantly increased in the temperature range of 120°C to 150°C, but the crosslinking density and mechanical properties of the reaction products decreased. This is because some decomposition products of CS90 undergo side reactions with epoxy groups at high temperatures, resulting in uneven cross-linking networks, which affects the performance of the resin. The study also pointed out that the optimal operating temperature range of CS90 is 20°C to 80°C. Within this temperature range, CS90 can maintain high catalytic activity and selectivity while avoiding decomposition or loss caused by excessive temperatures. live.

(2019) studied the catalytic behavior of CS90 under different humidity conditions through experiments, and found that under high humidity environment, the catalytic activity of CS90 has significantly decreased, the reaction rate slowed down, and the selectivity of reaction products has also decreased. They believe that the presence of moisture in high humidity will cause changes in the molecular structure of CS90, weakening its alkalinity and inability to effectively neutralize acidic substances in the reaction system, leading to an increase in side reactions and a decline in product quality.

Another study conducted by Zhang et al. (2021) focused on the impact of low humidity on CS90 performance. They found that the CS90-catalyzed epoxy resin curing reaction rate significantly increased under an environment of 10%, but the crosslinking density and mechanical properties of the reaction products decreased. This is due to insufficient moisture at low humidity, which leads to incomplete reaction between epoxy groups and amine-based curing agents, which affects the formation of the crosslinking network. The study also pointed out that the optimal operating humidity range of CS90 is 40% to 60%, and within this humidity range, CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation caused by excessive or low humidity. .

(2017) experimentally studied the catalytic behavior of CS90 under different air pressure conditions, and found that under high air pressure environment, the catalytic activity of CS90 has significantly decreased, the reaction rate slowed down, and the selectivity of reaction products has also decreased. They believe that the increase in the partial pressure of the gas at high air pressure leads to a slowdown in the diffusion rate of the reactants, which affects the progress of the reaction. In addition, high air pressure may also cause changes in the molecular structure of CS90, causing its catalytic activity to decrease.

Another study conducted by Brown et al. (2019) focused on the effect of low air pressure on CS90 performance. They found that the CS90-catalyzed epoxy resin curing reaction rate significantly increased at air pressure of 0.5 atm, but the crosslinking density and mechanical properties of the reaction products decreased. This is due to insufficient partial pressure of the gas at low air pressure, which leads to incomplete reaction between the epoxy group and the amine-based curing agent, which affects the formation of the crosslinking network. The study also pointed out that the optimal operating pressure range of CS90 is 0.8 atm to 1.2 atm, within which the CS90 can maintain high catalytic activity and selectivity while avoiding performance degradation caused by excessive or low air pressure. .
