摘　　要：以三甲基氯硅烷为原料,添加溶剂、缚酸剂、催化剂,合成了异丙烯氧基三甲基硅烷,探讨了催化剂种类及用量、缚酸剂种类及用量、溶剂种类、反应温度对目标产物收率的影响。结果表明,较佳条件为:催化剂选择无水三氯化铝,催化剂用量为三甲基氯硅烷质量的1.6%,缚酸剂选择三丙胺,三丙胺与三甲基氯硅烷的量之比为1.3∶1,溶剂选择丙酮,反应温度50℃。该条件下目标产物的收率为92%。Isopropenyloxytrimethylsilane has been synthesized from trimethylchlorosilane(as raw material),solvent,acid binding agent and catalyst.The effects of the types and content of catalyst and acid binding agent,the types of solvent,and the temperature on the yield of the target product are discussed.The results show that the optimum conditions are as follows:taking anhydrous aluminum trichloride as catalyst(1.6%of the mass of trimethylchlorosilane),tripropylamine as acid binding agent,the ratio of tripropylamine to trimethylchlorosilane is 1.3∶1,acetone as solvent,at 50℃,the yield of the target product is 92%.
