Abstract:
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 haloalkylalkoxysilane in the presence of a solid supported 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 a carboxylic acid halide and/or acid anhydride.
