Abstract
A process is provided for making methylchlorosilanes based on the reaction of methylchloride and particulated silicon, which has been contacted with a mixture of partially oxidized copper catalyst and copper formate. A reduction is achieved in the percent by weight of residue which are the silicon products in the methylchlorosilane crude having boiling points exceeding 70.degree. C. at atmospheric pressure, while the weight percent of disilane in such residue cleavable to useful chlorosilane monomer is not adversely affected.
