Abstract
The present invention is a process for converting a high-boiling component resulting from the reaction of an organochloride with silicon into commercially more desirable monosilanes. The process comprises contacting the high-boiling component with chlorine at a temperature within a range of about 250.degree. C. to 1000.degree. C. Improved yield of monosilanes can be obtained in the process by the use of a catalyst selected from a group consisting of alumina, silica. activated carbon, AlCl.sub.3, and AlCl.sub.3 supported on a support selected from a group consisting of alumina, silica, and carbon.
