ABSTRACT:
A process for the organooxylation of chlorosilanes. The process comprises contacting in a film a chlorosilane and an alcohol capable of forming an ester with the silicon of the chlorosilane and thereby forming an equilibrium mixture comprising an organooxysilane and hydrogen chloride. The film is heated at a temperature sufficient to cause vaporization of the hydrogen chloride from the equilibrium mixture thereby increasing the yield of organooxysilane in the equilibrium mixture. In a preferred process, the process is run in a falling-film type reactor or a wiped-film type reactor.
