Abstract: A process for preparing cyanoethyltrimethoxysilane is performed via transesterification of cyanoethyltriethoxysilane with methanol in the presence of a catalyst. The cyanoethyltrimethoxysilane is useful as an adhesion promoter, a coupling agent, or a crosslinker. The cyanoethyltrimethoxysilane may be formulated in a polyorganosiloxane sealant composition.
