Description
技术领域
本发明涉及化工生产领域，尤其是苯基三乙氧基硅烷生产领域。
背景技术
苯基三乙氧基硅烷是重要的化工原料，可作为硅树脂的交联剂，也可用作苯基硅油等高分子有机化合物的原料。
发明内容
本发明提供一种苯基三乙氧基硅烷生产工艺。详细流程：
（1）合成原理：
将苯基三氯硅烷和乙醇进行酯化反应制得苯基三乙氧基硅烷，并产生HCl。主要反应如下：
PHSiCl3 + C2H5OH → PHSi(OC2H5)3 + 3HCl
主要副反应为：
PHSiCl3 + C2H5OH → PHSiCl 2 (OC2H5)+ HCl
（2）工艺流程：
将苯基三氯硅烷加入反应釜，抽真空，升温到80℃，按规定的比例量连续加入乙醇，维持反应温度79℃，副产物氯化氢气体通过水流泵进行吸收成低浓度的盐酸。待乙醇加入完毕，将反应物转入蒸馏釜进行蒸馏分离，得到纯度大于97%的产品。
