Beschreibung
Zusammenfassung:	The invention discloses a method for synthesizing a bis-[triethoxypropylsilane]-disulphide silane coupling agent by virtue of an aqueous phase process. By taking water as a solvent, reaction is carried out on sodium hydrosulfide, trisodium phosphate, sulfur power and gamma-chloropropyltriethoxysilane in a two-phase reaction system in the presence of a catalyst. The method is low in production cost, high in safety, simple to operate, short in reaction time, high in conversion ratio, high in productive rate and high in main content and is suitable for industrial production.
