ABSTRACT:
A process for redistributing an alkyl-rich silalkylene-containing residues. The process comprises contacting an alkyl-rich silalkylene-containing residue with a halosilane selected from the group consisting of alkyltrihalosilanes and tetrahalosilanes in the presence of an effective amount of a redistribution catalyst at a temperature within a range of about 150.degree. C. to 500.degree. C. thereby forming a redistribution product comprising dialkyldihalosilane. At least a portion of the catalyst in the present process may be formed in situ during conduct of the direct process and isolation of the resulting monosilanes.
