A transesterification process for preparing alkoxysilane includes removal of metal transesterification catalyst from the alkoxysilane transesterification reaction medium.

Process for preparing alkoxysilanes

The invention is directed to a process for the preparation of thiocarboxylate silane comprising reacting an aqueous solution of a salt of a thiocarboxylic acid with a haloalkyl silane in the presence of a solid inorganic oxide-supported phase transfer catalyst. The invention is also directed to a process for the preparation of an aqueous solution of a salt of a thiocarboxylic acid which comprises reacting an aqueous solution of a sulfide and/or hydrosulfide with an acid halide in the presence of a said solid catalyst.
