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 hydrogen gas at a temperature within a range having a lower limit greater than 250 DEG C. and an upper limit of 1000 DEG C. Yield of the present process may be improved by use of a catalyst selected from a group consisting of activated carbon, platinum metal, platinum supported on alumina, palladium supported on carbon, SbCl5, H2PtCl6, BCl3, AlCl3, and AlCl3 supported on a support material selected from a group consisting of carbon, alumina, and silica. In a preferred embodiment of the present process the process is run at a pressure within a range of about 250-1000 psig. The present process is preferential for the production of diorganodichlorosilane in relation to organotrichlorosilane in the monosilane product.
