A process for the organooxylation of .beta.-cyanoalkyl- chlorosilanes. The process comprises contacting in a film a .beta.-cyanoalkylchlorosilane with an alcohol capable of forming an ester with the silicon of the .beta.-cyanoalkylchlorosilane and thereby forming an equilibrium mixture comprising a (.beta.- cyanoalkyl)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 yield of (.beta.-cyanoalkyl)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.
