ABSTRACT:
Organochlorosilanes are reacted with methanol in contact with a tetraorganophosphonium chloride catalyst to form organosiloxanes and methylchloride. The method avoids significant silicon-carbon bond cleavage and provides good conversion of the chlorine of the chlorosilane to methylchloride while avoiding undesirable dimethylether formation.
