Methylphenyldichlorosilane can be used as an organosilicon monomer and has a good market development prospect
Methylphenyl dichlorosilane, also known as dichloromethylphenylsilane, chemical formula is C7H8Cl2Si, the appearance is colorless transparent liquid, toxic, irritating, corrosive, soluble in methanol, ether and other organic solvents, hydrolyzed in water, flammable, open flame, high heat or contact with oxidant can be burned and decomposed to release toxic hydrogen chloride gas.
Methylphenyldichlorosilane can be used as an organosilicon monomer, an intermediate in organic synthesis, and used to prepare silicone polymers such as silicone oil, silicone resin, silicone rubber, and organosilicon compounds. Methylphenyldichlorosilane can be used to prepare methyl phenyl silicone oil, including high-temperature resistant silicone oil, terminated silicone oil, hydrogen-containing silicone oil, etc.; It can be used to prepare methyl phenyl silicone resin for plastics and coatings production, and methyl phenyl vinyl silicone resin for the production of encapsulants; It can be used to prepare methylphenyl silicone rubber.
According to the "2024-2029 China Methylphenyl Dichlorosilane Industry Market In-depth Research and Development Prospect Forecast Report" released by the New Thinking Industry Research Center, methylphenyl dichlorosilane can improve the high and low temperature resistance and chemical stability of silicone products, and can be widely used in construction, chemical industry, textile, electronics, electric power, medical, automobile, shipbuilding, aerospace and other fields. The global silicone market continues to grow and is expected to reach $17.6 billion by 2029. In the raw materials for the production of organic silicon industry, the demand for phenyl monomer is second only to methyl chlorosilane monomer, and methylphenyl dichlorosilane is one of the phenyl monomer products, and the market development prospect is good.
Methylphenyldichlorosilane can be prepared by Grignard method, condensation method, disproportionation method and other processes. The Grignard method is prepared by reaction of phenylmagnesium chloride and methyl trichlorosilane as raw materials; The condensation method also includes the heat shrinkage method and the catalytic shrinkage method, the former is prepared by condensation reaction under high temperature conditions, and the latter is prepared by condensation reaction under the action of catalyst.
In the organosilicon industry, dimethyl dichlorosilane is the most commonly used organosilicon monomer, and its preparation is usually by direct method, that is, methyl chloromethane and silicon powder are used as raw materials, and methyl chlorosilane mixture is prepared by reaction under the action of copper-based catalyst, and then separated by distillation, which will produce by-products with a boiling point higher than dimethyldichlorosilane in this process, that is, organosilicon high boiling matter, and methylphenyl dichlorosilane can also be prepared by using high boiling matter, so as to realize the reuse of waste resources and meet the requirements of sustainable development.
Industry analysts said that globally, methylphenyldichlorosilane manufacturers mainly include foreign companies such as Dow Chemical of the United States and Wacker Chemie AG of Germany, as well as domestic enterprises such as Zhejiang Xin'an Chemical Group Co., Ltd., Liaoning Xinbang New Materials Co., Ltd., Dalian Yuanyong Silicone Factory, Anhui Ayota Silicone Oil Co., Ltd., Zhejiang Jiahui New Materials Co., Ltd., and Tangshan Coupling Silicon Industry Co., Ltd.
