乙烯基三乙氧基硅烷上游产品

乙烯基三乙氧基硅烷下游产品

乙烯基三乙氧基硅烷制备

可由乙烯基三氯硅烷与无水乙醇反应来制取，也可由四乙氧基硅烷与乙烯基溴化镁反应来制取。

1、乙烯基三氯硅烷的合成将三氯硅烷加热后通入乙炔，最好在过氧化物、叔胺或铂盐之类的催化剂存在的情况下，在液相或气相中进行加成反应而制得。

2、乙烯基三乙基硅烷的合成

3.以三乙氧基氢硅和乙炔为原料，在二氯双三苯基磷和铂盐的催化作用下，一步加成制得产物。反应温度为90～130℃，合成反应式如下：

工艺有液相法和气相法两种。所谓液相法就是将三乙氧基氢硅和催化剂一并加入反应体系中，然后，将乙炔通入反应物料中进行反应。气相法中，催化剂是装载于管式反应器中，然后，将三乙氧基氢硅汽化，与乙炔混合后导入反应器中进行反应。
也可先合成乙烯基三氯硅烷，再使用乙烯基三氯硅烷与乙醇加热反应制得乙烯基三乙氧基硅烷；或在乙醇存在的条件下将乙烯基三氯硅烷与原甲酸三乙酯一起共热制得：
