| titleOfInvention | A kind of method that use double solvents, three component catalysts synthesize γ mercaptopropyltriethoxysilanes |
| abstract | The present invention provides a kind of method that use double solvents, three component catalysts synthesize γ mercaptopropyltriethoxysilanes, prepare including raw material, γ-chloropropyl triethoxysilane is added dropwise, the raw material prepares, and γ-chloropropyl triethoxysilane is 1 with anhydrous sodium hydrosulfide weight ratio:0.256 0.303, the double solvents is ethanol, butanone, dimethylformamide, and three component catalyst is sodium iodide, TMG, alcohol sodium alcohol solution；The alcohol sodium alcohol solution, caustic alcohol weight percentage is 18 21%.The purity of product prepared by the present invention is 99.51 99.56%；The yield of product is 95.1 95.4%；Chloropropyl triethoxysilane conversion ratio is 98.2 98.5%；The compounds content such as hydrolysate, jello, polymer polyoxy silane is 0.3 0.5% in product of the present invention；Reaction time shortens about 6 hours than existing process. |
