Conversion of direct process high-boiling component to chlorosilane monomers in the presence of chlorine

摘要

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 DEG C. to 1000 DEG 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, AlCl3, and AlCl3 supported on a support selected from a group consisting of alumina, silica, and carbon.
