Trimethylchlorosilane has a wide range of applications and the industry is developing well

Trimethylsilyl chloride, the chemical formula is C3H9ClSi, appears as a colorless and transparent liquid, has a pungent odor, is toxic, and is corrosive. Trimethylsilyl chloride will hydrolyze when exposed to water and is easily volatile. It will decompose to produce hydrogen chloride when exposed to humid air. It is soluble in organic solvents such as ether, benzene, and tetrachlorethylene. Trimethylsilyl chloride is flammable and can burn when exposed to open flames, high temperatures or oxidants. Trimethylsilyl chloride is an organic compound with a wide range of downstream uses.

The preparation method of trimethylsilyl chloride is as follows: using methyl chloride and silicon powder as raw materials, using cuprous chloride as the catalyst to react to obtain a crude product, and then undergoing distillation and purification to obtain the finished product; using tetramethylsilane and acetyl chloride as raw materials , prepared by adding aluminum trichloride as a catalyst; using trimethylsilyl ether as the raw material and converting it; using methylene chloride and hexamethyldisiloxane as the raw material and reacting, etc. In industry, the first one-step synthesis method is usually used to prepare trimethylchlorosilane, which has the advantages of high production efficiency and mild reaction conditions.

According to the “Trimethylchlorosilane Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” released by the Industrial Research Center , Trimethylchlorosilane can be used in the chemical industry as raw materials and organic synthesis intermediates to prepare a variety of organosilicon compounds and silylated derivatives, such as hexamethyldisiloxane (silyl ether), hexamethyldisiloxane Disilazane, trimethylsilyl cyanide, silicone oil, polysilicone, methyl silicone oil sealing agent, etc. can also be used in the field of polycrystalline silicon preparation. Trimethylsilyl chloride can be used in the pharmaceutical field to prepare pharmaceutical intermediates such as 7-aminocephalosporanic acid (7-ACA) and to produce cephalosporin antibiotics. In addition, trimethylchlorosilane can also be used in spices, gas chromatography analysis reagents and other fields.

In overseas markets, the main manufacturers of trimethylchlorosilane include WACKER of Germany, Evonik of Germany, DOW of the United States, Momentive of the United States, Cabot of the United States, Japan’s TOKUYAMA, South Korea’s OCI, etc. In the Chinese market, the main manufacturers of trimethylchlorosilane include GCL-Poly Energy Holdings Co., Ltd., Tangshan Sanfu Silicon Industry Co., Ltd., Henan Shangyu New Energy Co., Ltd., Zhejiang Xin’an Chemical Group Co., Ltd., etc.

Industry analysts said that trimethylchlorosilane plays an important role in the silicon industry chain. Due to the introduction of trimethylsilane, It can be used as a protective group for hydroxyl, carboxyl, amino and other functional groups, and is widely used in organic synthesis. As the scale of my country’s electronics industry and solar energy industry continues to expand, the demand for silicon products in the Chinese market continues to grow. Especially with the rapid development of the new energy power generation industry, the demand for trimethylchlorosilane continues to rise. Generally speaking, my country’s trimethylchlorosilane industry is developing well. However, compared with foreign companies, the production scale of trimethylchlorosilane of a single domestic company is relatively small, and there is still much room for improvement in the future.
