ABSTRACT:
A process for the preparation of acyloxysilanes. The process comprises contacting a chlorosilane with a carboxylic acid in a film forming an equilibrium mixture of acyloxysilane 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 acyloxysilane in the equilibrium mixture. In a preferred process, the process is run in a falling-film type reactor or a wiped-film type reactor.
