PREPARATION OF ALKOXYSILANES BY ETHERIFICATION OF CHLOROSILANES WITH REMOVAL OF HYDROGEN CHLORIDE BY VAPOR OF THE BOILING SOLVENT.

Etherification of chlorosilanes with alcohols is the usual method of obtaining alkoxysilanes. Hydrogen chloride formed as a byproduct must be removed so as to avoid side reactions and increase the yield. The vapor of boiling solvent was used as an agent to remove hydrogen chloride from the reaction zone. Various solvents were tried and their effect on yield was studied. Removal of hydrogen chloride with the vapor of the boiling solvent during etherification of chlorosilanes makes it possible to obtain alkoxysilanes in 80-90% yield as the result of strong suppression of side reactions.
