γ-（2，3-环氧丙氧）丙基三甲氧基硅烷的合成研究

摘要

以三甲氧基氢硅与烯丙基缩水甘油醚为原料，在氯铂酸-N，N-二甲基苯胺一异丙醇溶液为催化剂下硅氢加成反应得γ-（2，3-环氧丙氧）丙基三甲氧基硅烷，讨论了影响硅氢加成反应的主要因素，并得出了最佳合成工艺条件：催化剂用量为4×10^-6、反应温度95℃～105℃、反应时间为1．5h、原料配比三甲氧基氢硅／烯丙基缩水甘油醚摩尔比为1．05，在此条件下γ-（2，3-环氧丙氧）丙基三甲氧基硅烷的收率达89．3％。%γ-glycidoxypropyltrimethoxysilane （KH-560） was synthesized directly from allylglycidylether and trimethoxysilane catalyzed by chloroplatinic acid-N,N-dimethylaniline-isopropanal system.The main effects of the reaction on the yield were discussed and the optimum experimental conditions were found.The results showed that the yield of KH-560 reached 89.3% at 95 ℃-105℃,while the catalyst dosage of 4×10^-6, the molar ratio of trimethoxysilane： allylglycidylether of 1.05,and the reaction time of 1.5 h were chosen.
