| titleOfInvention | Preparation method of sulfur-containing silane coupling agent |
| abstract | The invention discloses a process for preparing a sulfur-containing silane coupling agent by using a supported quaternary ammonium salt phase transfer catalyst and taking polysulfide aqueous solution and 3-halopropyl trialkoxy silane as raw materials. Compared with the two-phase transfer catalyst adopted in the prior art for preparing the sulfur-containing silane coupling agent, the supported quaternary ammonium salt phase transfer catalyst has the characteristic of insolubility in water, acid, alkali and organic solvent, and can be directly filtered, washed and dried after being used, so that the catalyst can be recycled. The sulfur-containing silane coupling agent prepared by the method provided by the invention has the environmental protection advantages of recoverable catalyst, no influence on the yield and quality of the product, easy separation of the product, low production cost, no residue of the catalyst in a water phase or an organic phase and the like. |
