colorless flammable liquid, high toxicity. Boiling Point 201 °c. The relative density was 1. 321. Refractive index 5240. Flash point 85. Soluble in benzene, ether, perchloroethylene, water, even trace water in the air, that is, the occurrence of intense hydrolysis reaction, and the release of hydrogen chloride.
In the presence of copper catalyst, chlorobenzene and silicon powder are directly synthesized in one step to obtain crude monomer, and the product phenyltrichlorosilane is obtained by distillation, and the by-product diphenyldichlorosilane is obtained. The mixed monomer composition is generally 30% of phenyltrichlorosilane and 8% of diphenyldichlorosilane.
This product is used to prepare phenyl silicone resin.
