Abstract
An improved process for making an alkyl halide and organosiloxanes from a dialkyldialkoxysilane and a hydrogen halide is disclosed. Dialkyldialkoxysilane and hydrogen halide are simultaneously introduced at respective feed points into a column containing hydrogen halide under reflux in such proportions that the amount of hydrogen halide introduced into the column is at a stoichiometric excess over the dialkyldialkoxysilane. In preferred embodiments, the hydrogen halide is hydrogen chloride; the dialkyldialkoxysilane is dimethyldimethoxysilane; the alkyl halide is methyl chloride; and the organosiloxanes are predominantly of the cyclic type.
