Title: Improvements in and relating to alkylation of halogenosilanes
IPC: C07F7/12
Filed: 1946-03-08
Abstract: Alkylhalogenosilanes containing at least two silicon bonded methyl or ethyl radicals are prepared by bringing a gaseous mixture of an alkylhalogenosilane containing at least two silicon bonded halogen atoms and at least one silicon bonded methyl or ethyl radical and a methyl or ethyl halide into contact at an elevated temperature with aluminium or zinc, e.g. at a temperature between 300 DEG  and 500 DEG C.  In examples: (1) vapours of dimethyldichlorosilane and methyl chloride are reacted in the presence of heated aluminium to yield trimethylchlorosilane, unreacted dimethyldichlorosilane and silicon tetramethyl; (2) and (3) methyltrichlorosilane is reacted with methyl chloride in the vapour state with or without hydrogen in the presence of heated aluminium to yield a mixture of methyl-, dimethyl- and trimethylchlorosilane; (4) trimethylbromsilane is prepared by passing the vapours of dimethyldibromsilane and methyl bromide over heated aluminium; (5) dimethyldichlorosilane and ethylchloride are reacted as in (4) to yield dimethylethylchlorosilane; (6) vapours of dimethyldichlorosilane and methyl chloride are reacted in the presence of heated zinc to give trimethylchlorosilane and unchanged dimethyldichlorosilane. The process of the invention may be applied to the alkylation of mixtures of mono- and dialkylhalogenosilanes. The alkyl content p  of more complex mixtures of halogenosilanes, e.g. those resulting from the reaction of silicon and an alkyl halide in accordance with Specification 575,667, may be increased by the process of the invention with or without the aid of an additional alkyl halide.  The Specification as open to inspection under Sect. 91 refers generally to the alkylation of halogenosilanes containing at least two halogen atoms and at least one silicon bonded monovalent hydrocarbon radical, e.g. methyl, ethyl or phenyl radicals, by a similar process using a lower alkyl halide as the alkylating agent. This subject-matter does not appear in the Specification as accepted.
