FIELD: chemistry.
SUBSTANCE: invention relates to Grignard processes for obtaining phenyl-containing chlorosilane products. Claimed are three versions of Grignard process for obtaining diphenylchlorosilanes. In first version Grignard process reagents are phenyl Grignard reagent, solvent from class of ethers, trichlorosilane and toluol. In second version Grignard process reagents are phenyl Grignard reagent, solvent from class of ethers, phenylchlorosilane and solvent for combination reaction from class of aromatic hydrocarbons. In third version Grignard process reagents are phenyl Grignard reagent, solvent from class of ethers, trichlorosilane, phenylchlorosilane and solvent for combination reaction from class of aromatic hydrocarbons. In each version reagents are present in definite molar ratio.
EFFECT: elaboration of Grignard process in which output of diphenylchlorosilanes as product is maximized and output of phenylchlorosilanes as product is minimised.
