Abstract:
The instant invention provides a process for reducing chloride content from by-products generated during production of methylchlorosilanes, comprising, (a) hydrolyzing the by-products by combining the by-products with an aqueous medium, the aqueous medium optionally comprising a surfactant, at a pH of at least about 7 and at a temperature above about 0. degree. C. to yield a first phase comprising essentially solids and a second phase comprising an aqueous phase; (b) separating the first and second phase; and (c) oxidizing the solids from the first phase at a temperature of at least about 300. degree. C. for up to about 24 hours to yield a residue comprising less than about 1% by weight of chloride. The solids from the first phase may alternatively be reduced under a hydrogen flow, at a temperature of at least about 500. degree. C. for up to about 24 hours.
