摘　　要：以乙烯基三氯硅烷(ViSiCl_3)、甲醇(MeOH)及乙二醇甲醚为主要原料,采用醇解、酯交换两步反应合成了ViSi(OEtOMe)_3。确定了其最佳醇解反应条件为:n(ViSiCl_3):n(MeOH)为1:3.6,反应温度为80℃,在此条件下中间体ViSi(OMe)_3收率在85%左右;最佳酯交换反应条件为:n(ViSi(OMe)_3):n(乙二醇甲醚)为1:3.6,反应温度为100℃,反应时间为1.5～2.0h,产物ViSi(OEtOMe)_3酯交换的单程收率可达到92%。最后采用GC-MS法对最终产物结构进行了表征。Vinyl tri（2-methoxyethoxy）silicane was synthesized with vinyl trichlorosilane,methanol and ethylene glycol monomethyl ether through alcoholysis and transesterification reaction.The results showed that the optimal alcoholysis reaction conditions were found as follow：n（vinyl trichlorosilane）：n（methanol） = 1：3.6,the reaction temperature was 80℃,the yield of vinyltrimethoxysilane can reach 85%.When n（ViSi（OMe）3）：n （ethylene glycol monomethyl ether） = 1：3.6,reaction temperature was 100℃and reaction time can be identified as 1.5～2.0h,the single-pass yield of transesterification can reach 92%at the optimal condition.At last,the target product was characterized by GC-MS.
