Overview of traditional catalysts

Traditional catalysts have a long history in the chemical industry and are of various types, mainly including metal salts, amines, etc. Although they perform well in some respects, there are obvious shortcomings in environmental protection and safety. In order to better understand the characteristics of traditional catalysts, this section will introduce in detail from the aspects of chemical composition, physical and chemical properties, application fields, etc., and compare it with the 9727 catalyst.

1. Chemical composition and structure

The chemical composition of traditional catalysts varies by type. The following are the chemical composition and characteristics of several common traditional catalysts:

  • Tindalate Octoate: This is a commonly used organic tin catalyst, widely used in polyurethanes and epoxy resins.?Current reaction. Its chemical formula is Sn(C8H15O2)2, which has high catalytic activity, but has a large odor and high VOC emissions.

  • Dilaurel di-n-butyltin (DBTDL): The same DBTDL component as the 9727 catalyst, but traditional DBTDL catalysts usually do not contain additives, resulting in a heavier odor and a higher VOC content.

  • Diethyl Zinc: This is a powerful metal catalyst commonly used in organic synthesis reactions. Its chemical formula is Zn(C2H5)2, which has high reactivity, but is highly toxic, and is prone to react with the moisture in the air to produce harmful gases.

  • Amine catalysts: such as triethylamine (TEA), dimethylcyclohexylamine (DMCHA), etc. These catalysts perform well in polyurethane reactions, but have a strong odor and are easy to use with Isocyanate undergoes side reactions, affecting product quality.

2. Physical and chemical properties

The physical and chemical properties of traditional catalysts are closely related to their chemical composition. The following are the main physical and chemical parameters of several common traditional catalysts:

Catalytic Type Appearance Density (g/cm³) Viscosity (mPa·s, 25°C) Smell VOC content (g/L) Thermal Stability (°C)
Shinyasin Light yellow transparent liquid 1.10-1.15 100-200 Medium 100-200 150-180
Dilaurel di-n-butyltin Light yellow transparent liquid 1.05-1.10 50-100 Heavier 80-150 200-220
Diethylzinc Colorless transparent liquid 0.90-0.95 1-5 None 0 100-120
Triethylamine Colorless transparent liquid 0.72-0.75 1-5 Strong 50-100 100-120

From the table above, it can be seen that the odor and VOC content of traditional catalysts are generally high, especially in cinnamonite and amine catalysts. In addition, the thermal stability of traditional catalysts is relatively poor, and they are prone to decomposition or inactivation at high temperatures, affecting the catalytic effect.

3. Application areas

Traditional catalysts still occupy an important position in many fields due to their wide applicability and low cost. The following is a detailed introduction to its main application areas:

  • Polyurethane industry: Traditional catalysts such as cinnamon and dilaurite dinbutyltin are widely used in the production of polyurethane foams, elastomers, adhesives and other products. They can effectively promote the reaction of isocyanate with polyols, but due to the large odor and high VOC emissions, they are gradually replaced by low-odor catalysts.

  • Epoxy resin industry: Traditional catalysts such as diethyl zinc, triethylamine, etc. perform well in the curing reaction of epoxy resins, but their toxicity and odor problems limit their environmental protection Applications in the product.

Comparison of the cost of low-odor reaction 9727 catalyst with traditional catalyst

In the chemical industry, cost is one of the important factors that companies consider when choosing catalysts. This section will conduct a detailed comparison of the low-odor reactive 9727 catalyst with traditional catalysts from the aspects of raw material costs, production costs, transportation costs, and usage costs to evaluate the economics of the two.

1. Raw material cost

The raw material cost of the catalyst is one of the key factors affecting its total cost. The main raw material of the 9727 catalyst is dilauri dibutyltin (DBTDL), which has a relatively high market price, but by optimizing the production process and large-scale production, unit costs can be effectively reduced. In contrast, the raw materials of traditional catalysts are relatively low, especially metal salts and amine catalysts. Due to their simple production process and wide sources of raw materials, the cost advantage is obvious.

According to data from market research institutions, the average global price of dibutyltin in 2022 is about US$20-25/kg, while the price of sin sin is about US$10-15/kg, and the price of triethylamine is even lower , about 5-8 USD/kg. Specific price fluctuations are affected by factors such as market demand and raw material supply, but overall, the raw material cost of traditional catalysts is lower than that of 9727 catalysts.

2. Production Cost

Production costs include the costs of catalyst manufacturing, packaging, testing and other links. The production process of 9727 catalyst is relatively complex and requires multiple reaction and refining processes, so the production cost is relatively high. However, with the advancement of technology and the renewal of production equipment, the production efficiency of 9727 catalysts has been continuously improved and the unit cost has gradually decreased. In addition, the production process of 9727 catalyst is more environmentally friendly and complies with strict environmental protection standards, reducing the environmental governance costs of the enterprise.

The production process of traditional catalysts is relatively simple, with short production cycle and equipment investment, therefore, the production cost is lower. However, traditional catalysts will generate more waste gas, waste water and waste slag during the production process, which increases the company’s environmental protection management costs. For example, a large amount of ammonia will be released during the production process of amine catalysts, and exhaust gas must be treated; a heavy metal-containing wastewater will be produced during the production process of metal salt catalysts, and special sewage treatment will be required. These additional environmental costs make the actual production cost of conventional catalysts not as cheap as they appear.

3. Transportation Cost

The transportation cost mainly depends on the density of the catalyst, packaging method and transportation distance. The density of the 9727 catalyst is low, about 1.05-1.10 g/cm³, so it occupies a large space during transportation and has a relatively high transportation cost. However, the packaging of the 9727 catalyst is usually made of sealed barrels or IBC tons, which can effectively prevent leakage and contamination and reduce risks during transportation.

The density of traditional catalysts is higher, especially metal salt catalysts, such as stannous oxide, which has a density of 1.10-1.15 g/cm³, so it occupies less space during transportation and has a lower transportation cost. However, traditional catalysts have a high odor, which can easily cause pollution to the transportation tools and the surrounding environment, increasing safety risks and cleaning costs during transportation.

4. Cost of use

Usage cost refers to the consumption and maintenance cost of the catalyst in actual application. The 9727 catalyst has high catalytic activity and can achieve ideal catalytic effects at a lower dosage, so it is cheaper to use. In addition, the 9727 catalyst has extremely low odor and less VOC emissions, which reduces the company’s investment in ventilation, exhaust gas treatment, etc., and further reduces the cost of use.

The catalytic activity of traditional catalysts is relatively low, especially in low temperature or high humidity environments, the reaction speed is slow, resulting in an increase in the amount and an increase in the cost of use. In addition, traditional catalysts have a high odor and VOC emissions are high. Enterprises need to invest more resources in ventilation, exhaust gas treatment and employee protection, which increases the cost of use.

Comparison of environmental impacts

With the increasing global environmental awareness, the environmental impact of catalysts has become one of the important considerations when companies choose catalysts. This section will provide a detailed comparison of the environmental impact of low-odor reaction 9727 catalysts and traditional catalysts from the aspects of VOC emissions, toxicity, waste treatment, etc.

1. VOC emissions

VOC (volatile organic compounds) is a type of substance that is harmful to the environment and human health and is widely present in chemical production processes. The VOC content of the 9727 catalyst is extremely low, usually less than 50 g/L, which is much lower than the VOC content of traditional catalysts. For example, the VOC content of sinocyanide is about 100-200 g/L, and the VOC content of triethylamine is about 50-100 g/L. Lower VOC emissions allow the 9727 catalyst to have no adverse effects on the environment and operators during use, and comply with increasingly stringent environmental regulations.

The VOC emissions of traditional catalysts are high, especially in amine catalysts. High VOC emissions not only cause air pollution, but also cause harm to human health, such as respiratory diseases, skin allergies, etc. Therefore, when enterprises use traditional catalysts, they must take effective waste gas treatment measures, which increases production costs and environmental burden.

2. Toxicity

The toxicity of catalysts is one of the important indicators to measure their environmental friendliness. The main component of the 9727 catalyst is dilauri dibutyltin, which is low in toxicity and is a micro-toxic substance, complying with the relevant requirements of the EU REACH regulations and the US EPA. In addition, the additives in the 9727 catalyst have also been strictly screened to ensure that they are harmless to the human body and the environment.

The toxicity of traditional catalysts varies greatly, and some of them have high toxicity. For example, diethyl zinc is a powerful metal catalyst, but it is highly toxic and easily reacts with moisture in the air to produce harmful gases. Amines catalysts such as triethylamine are also toxic, and long-term exposure may lead to symptoms such as headache, nausea, and difficulty breathing. Therefore, when using traditional catalysts, enterprises must take strict safety protection measures to ensure the health of operators.

3. Waste treatment

Waste treatment of catalysts is also an important aspect of evaluating their environmental impact. The waste disposal of the 9727 catalyst is relatively simple, mainly recycling unreacted catalysts and treating a small amount of waste liquid. Because the 9727 catalyst has extremely low odor and low VOC emissions, there will be no secondary pollution during waste treatment, which meets environmental protection requirements.

The waste treatment of traditional catalysts is relatively complicated, especially metal salt catalysts. For example, the waste of stannous sineide contains heavy metals. It must be specially treated to avoid contamination of soil and water. Waste treatment of amine catalysts also faces challenges. Due to its strong odor and high VOC emissions, it is easy to pollute the surrounding environment during waste treatment. Therefore, when companies use traditional catalysts, they must invest more resources in waste treatment, which increases the environmental burden.

Market prospects and development trends

With the increasing strict global environmental regulations and the increasing demand for green products by consumers, the low-odor reactive 9727 catalyst has broad application prospects in the market. This section will analyze the market prospects of 9727 catalyst from market demand, policy support, technological innovation and other aspects, and look forward to its future development trends.

The U.S. Environmental Protection Agency (EPA) has also issued similar regulations requiring companies to reduce VOC emissions and promote the use of low-odor, low-VOC emission catalysts.

In China, the government attaches great importance to environmental protection and has introduced a series of policies and measures to encourage enterprises to adopt green chemical technology and environmentally friendly products. The “14th Five-Year Plan for Ecological Environment Protection” released in 2021 clearly proposes that we should vigorously develop the green chemical industry and promote low-VOC emission coatings, adhesives and other products. The implementation of these policies provides strong guarantees for the promotion and application of 9727 catalyst.

3. Technological innovation

Technical innovation is the core driving force for the development of the low-odor catalyst market. In recent years, with the development of cutting-edge technologies such as nanotechnology and molecular design, major breakthroughs have been made in the research and development of catalysts. For example, researchers have improved the molecular structure of the catalyst, which has improved its catalytic activity and selectivity, reducing odor and VOC emissions.

By analyzing the molecular structure of LOR-9727, the researchers found that its main chain contains a large number of hydroxy and carboxy functional groups, which can weakly interact with the moisture in the air, thereby effectively adsorbing and neutralizing volatile organic compounds. (VOCs), reduces the odor emission.

In addition, the cross-linking reaction mechanism of LOR-9727 also plays an important role in reducing odor. When LOR-9727 reacts with the multifunctional crosslinking agent, a highly crosslinked three-dimensional network structure is formed, which not only improves the mechanical properties of the coating film, but also effectively blocks the VOCs release channel, further reducing the odor emission . According to foreign literature reports, this crosslinking mechanism can reduce the release of VOCs to less than 1/10 of traditional coatings (Smith et al., 2021).
