A process for treating methylchlorosilanes by-products

摘要

The instant invention relates to a novel process for the hydrolysis of the by-products produced during the manufacture of methyldichlorosilanes comprising combining the by-products with an aqueous medium, optionally comprising a surfactant, at a pH range of at least about 7 and at a temperature of above about 0°C to produce a solid material in which copper and other metals are retained in a solid phase thereby resulting in a product with a high copper content.
