摘要
用不同配体的Pt配合物催化三甲氧基硅烷(TMOS)与1,2-环氧-4-乙烯基环己烷(EVCX)的硅氢加成反应合成了β-(3,4-环氧环己基)乙基三甲氧基硅烷.通过气质联用仪对反应产物进行分析,确定了主产物的结构.讨论了催化剂用量、反应温度等条件对反应的影响,筛选出了最佳的的反应条件.Pt-C38H34N2P2催化剂用量为40ppm表现出最佳的催化活性,当反应控温在80-90℃之间,β-(3,4-环氧环己基)乙基三甲氧基硅烷的产率可达80%以上.
β-（3,4-Epoxycyclohexyl） ethyl trimethoxysilane were synthesized by the platinum complexes catalyzed hydrosilation reaction of trimethoxysilane and 1,2-epoxy-4-vinylcyelohexane. The products were analyzed by means of GC-MS, and the effects of reaction temperature, the kind of catalyst, and the amount of catalyst on the production rate were discussed. The self - made catalyst has higher catalytic activity. Yield of the addition product can reach 80% under the temperature 80-90 ℃.
