Abstract
A process for reducing the chlorocarbon content of alkylsilanes is described. The process comprises (A) contacting crude alkylsilanes, containing as a minor portion chlorocarbons, and a hydrogen-containing silane with a catalyst; wherein the catalyst is a sufficient amount of an effective Lewis acid forming material; (B) facilitating the reaction of the chlorocarbons with the hydrogen-containing silane in contact with the catalyst to convert the chlorocarbons to a linear or branched alkanes; (C) separating catalyst from the alkylsilanes and alkanes; and (D) recovering alkylsilanes with lowered chlorocarbon content.
