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 more commercially desirable monosilanes. The process comprises contacting the high-boiling component with chlorine at a temperature within a range of 250°C. to 1000°C. Improved process yield of monosilanes is obtained by the use of a catalyst selected from alumina, silica, activated carbon, AlCl₃ and AlCl₃ supported on a support selected from alumina, silica and carbon.
