Phenylchlorosilane is a kind of intermediate which has a wide range of uses and is also one of the important monomers in the preparation of organosilicone polymers. It has obvious effect on improving the performance of polysiloxane, especially on improving the heat resistance, chemical stability and radiation resistance of silicone products. It not only has a wide range of applications in the fields of electronics, new energy vehicles, but also has a wide range of applications in aerospace, military industry, insulation and anti-corrosion materials and other fields.
Phenyl chlorosilane includes phenyl trichlorosilane, diphenyl dichlorosilane and other new special monomers. Compared with methyl organosilicate monomer, phenyltrichlorosilane can also improve the comprehensive properties of the material, but diphenyltrichlorosilane plays a decisive role in improving the high and low temperature resistance, weather resistance, radiation resistance and other aspects of the product.
Because phenylchlorosilane, especially diphenyldichlorosilane, has some special applications in aerospace and other fields, western countries have imposed technical blockade on us. China's phenylchlorosilane industry, especially diphenyldichlorosilane development is relatively slow, most of the equipment is small scale, backward technology production equipment, product quality, safety and environmental protection have some deficiencies and deficiencies. Correspondingly, the derivative industry of phenyl chlorosilane is more backward. Preparation of phenyl trichlorosilane preparation of phenyl trichlorosilane has direct method, thermal shrinkage method and Grignard method three processes.
