摘　　要：对甲基乙烯基二氯硅烷的乙醇解反应进行了理论(采用B3LYP/6-31G(D)方法)和实验(溶剂法)研究,发现反应较容易进行.主产物为甲基乙烯基二乙氧基硅烷;反应宜按乙醇滴加入氯硅烷的方式进行.理论和实验结果比较吻合.计算溶剂效应,表明溶剂的存在有利于排除副产物HCl的干扰,阻碍副反应的进行.The alcoholysis of dichloromethylvinylsilane was studied theoretically and experimentally. The reaction is very easy to proceed. Diethoxylmethylvinylsilane is the main product. And the mode of dropping （ethanol dropping into the solvent of dichloromethylvinylsilane） was used as well. The results of the calculation are consistent with those of the experiments. The solvent effect was also studied. The results showed that the solvent is of advantage to getting rid of the disturbing of HC1. The by-reaction could be baffled by solvent.
