摘要：
A method of purifying alkoxysilanes contaminated by organosilicon compounds with hydrolyzable chlorine atoms is disclosed wherein the alkoxysilanes are reacted in a pressure reactor with an alcohol, preferably in the presence of an HCl acceptor, at a temperature of 5.degree. C. to 160.degree. C. above the boiling point of the alcohol used and at the pressure which develops in the reactor.
