METHOD OF MAKING PHENYL-CONTAINING CHLOROSILANES WITH ALIPHATIC OR CYCLOPARAFFINIC HYDROCARBON SOLVENTS

Phenylmethyldichlorosilanes and diphenylmethylchlorosilanes are prepared by a Grignard process involving the step of contacting a phenyl Grignard reagent, an ether solvent, a trichlorosilane, and an aliphatic or cycloparaffinic hydrocarbon coupling solvent; in a mole ratio of the ether solvent to the phenyl Grignard reagent is 2 to 5, the mole ratio of the trichlorosilane to the phenyl Grignard reagent is 0.1 to 10, and the mole ratio of the aliphatic or cycloparaffinic hydrocarbon coupling solvent to the phenyl Grignard reagent is 3 to 7. Preferred reactants include phenylmagnesium chloride as the phenyl Grignard reagent; diethyl ether as solvent; n-heptane as the aliphatic hydrocarbon coupling solvent, or cyclohexane as the cycloparaffinic hydrocarbon coupling solvent; and methyltrichlorosilane.

ETHERIFICATION OF METHYLTRICHLOROSILANE WITH ALIPHATIC ALCOHOLS.

The authors report the results of a study of etherification of MTCS with C//2-C//4 aliphatic alcohols. It is shown experimentally that the rate of etherification of MTCS falls with increase of the molecular weight of the aliphatic alcohol. Etherification is slower with alcohols of branched structure than with the corresponding alcohols of normal structure. The rate of etherification of MTCS decreases with decrease of the number of chlorine atoms in the organochlorosilane molecule, and the final stage is reversible.
