摘　　要：以双(三氯硅基)乙烷为原料,通过醇解反应制备了双(三乙氧基硅基)乙烷。研究了溶剂种类、进料方式、醇解温度、反应时间、原料配比、氮气流速对双(三乙氧基硅基)乙烷收率的影响。较佳工艺为:双(三氯硅基)乙烷与乙醇的量之比1∶6.5,正己烷作溶剂,原料于40~50℃滴入乙醇,同时以50 m L/min的流速通入氮气吹除HCl气体,此条件下产物的收率可达95%。The 1,2 - bis （ triethoxysilyl ） ethane was prepared by alcoholysis of 1,2 - bis （trichlorosilyl） ethane as the raw materials. The effects of solvent types, feeding ways, alcoholysis temperature, reaction time, recipe of the raw materials, and the flow rate of nitrogen on the reaction were studied. The optimized re- action conditions were as follows ： the mole ratio of raw material and ethanol was 1 ： 6. 5, hexane as the sol- vent, ethanol dropwised at 40 -50℃, then purged HC1 gas by nitrogen at a flow rate of 50 mL/min. The yield of the final product reached to 95% under the conditions.
