  • Catalytic process for the preparation of thiocarboxylate silane
    Patent number: 9206203
    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 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.

  • Process for manufacture of blocked mercaptosilane coupling agents
    Patent number: 8097743
    Abstract: Blocked mercaptosilanes can be manufactured by reacting mercaptosilanes with organic or inorganic halides or anhydrides in the presence of an acid acceptor and washing the resulting reaction product with water/brine to yield two immiscible phases: an organic phase containing blocked mercaptosilane product and an aqueous phase containing the salt of the acid acceptor. Recycle of the acid acceptor is achieved by adding base to the aqueous phase. The process is suitable to be run in either batch or continuous mode. The blocked mercaptosilane compounds are used as coupling agents in rubber mixtures.
