Abstract
The described invention is a process for reducing residual organic chlorides in a crude phenylchlorosilane mixture. The process involves contacting the organic chloride with a Lewis acid forming material, in the presence of a phenyl source. The phenyl source can be the phenylchlorosilanes and other sources of phenyl present in the crude phenylchlorosilane mixture. The organic portion of the organic chloride forms a hydrocarbon adduct with the phenyl source. If desired, the hydrocarbon adduct can be easily separated from the phenylchlorosilanes.
