ABSTRACT:
An aqueous process is described in which thiocarboxylate silane is produced from haloalkyl silane by reaction of the haloalkyl silane with an aqueous solution of thiocarboxylate salt. Also described is a process for the preparation of aqueous thiocarboxylate salt from a sulfide and/or hydrosulfide and an acid chloride and/or acid anhydride.
