Tributyl phosphate (TBP) production technology continues to advance, and tributyl phosphate defoamer is its end product

Tributyl phosphate (TBP), also known as n-butyl phosphate, has a chemical formula of C12H27O4P (C4H9) 3PO4 and is an organic compound. Tributyl phosphate appears as a colorless liquid with a pungent odor. It is miscible in a variety of organic solvents and slightly soluble in water. Tributyl phosphate has the advantages of good chemical stability, good heat resistance and low toxicity. It is widely used in coatings, pesticides, organic synthesis, adhesives, inks and other fields.

In recent years, the production technology of tributyl phosphate has been continuously improved, mainly including phosphorus pentoxide butanol method, phosphorus oxychloride butanol method, phosphorus oxychloride butanol sodium method, etc. The phosphorus pentoxide butanol method uses phosphorus pentoxide and butanol as the main raw materials, and then undergoes full reaction, purification and other processes to obtain finished products. This method has many by-products and difficulty in purification, and is not suitable for large-scale production. ; The phosphorus oxychloride butanol method has the advantages of low production cost and simple process flow, and is the mainstream synthesis method of tributyl phosphate; the sodium phosphorus oxychloride butanol method has problems such as high production cost and poor safety, and is currently only used for During laboratory development.

According to the “2023-2028 China Tributyl Phosphate (TBP) Industry Market In-depth Research and Development Prospects Forecast Report>> shows that tributyl phosphate is widely used in coatings, pesticides, organic synthesis, adhesives, inks and other fields. Taking pesticides as an example, tributyl phosphate can be used to improve and enhance the performance of pesticides and enhance their bactericidal effect. Tributyl phosphate defoamer is an end product of tributyl phosphate. It has the advantages of good controllability, low toxicity, strong foam suppression, good permeability, and low dosage. It can be used in the production of inks, coatings, and putty slurries. Body and cement mortar, etc. In recent years, with the improvement of technological maturity, my country’s tributyl phosphate defoaming agent production capacity and output have continued to increase, which provides favorable conditions for the development of the tributyl phosphate industry.

The major global manufacturers of tributyl phosphate include Germany’s Lanxess Chemical Co., Ltd. (LANXESS) and the United States’ Sigma Aldrich Company (Sigma). Compared with overseas developed countries, my country’s tributyl phosphate industry started late, and the high-end competitiveness of local enterprises needs to be improved. The main manufacturers of tributyl phosphate in my country include Wuxi Zhenhu Chemical Co., Ltd., Mianyang Venus Phosphate Chemical Co., Ltd., Kaifeng Jiuhong Chemical Co., Ltd., Jiangsu Huajin Chemical Technology Co., Ltd., Yingde Donghong Chemical Technology Co., Ltd., etc. There are many participants in my country’s tributyl phosphate market. The market is dominated by small and medium-sized enterprises, and the industry concentration is low.

           Industry analysts said that as a multifunctional compound, tributyl phosphate has a wide range of applications and good industry development prospects. In the future, with the gradual release of market demand, the development speed of my country’s tributyl phosphate industry will accelerate. In terms of market competition, my country’s tributyl phosphate industry is relatively low-concentration, with local companies focusing on the production of mid- to low-end products, and high-end demand mostly relying on imports. In the future, with the continuous advancement of technology, my country’s tributyl phosphate industry will gradually develop in a high-end direction.
