Method for preparing epoxy terminated silicone oil with low olefin residue

The invention relates to a method for preparing epoxy-terminated silicone oil with low olefin residue. In a microchannel reactor and a continuous overflow reaction kettle, end hydrogen-containing silicone oil and allyl glycidyl ether are used for preparing the epoxy terminated silicone oil at the temperature of 50-90 DEG C under the catalysis of an enhanced Speier platinum catalyst. The method solves the problems of more double-bond isomerization impurities, longer reaction time and the like of the allyl glycidyl ether raw material in the existing industrial production method, and obviously reduces the emission of organic waste liquid and waste gas. 本发明涉及一种制备低烯烃残留的环氧封端硅油的方法。在微通道反应器及连续溢流反应釜中，用端含氢硅油和烯丙基缩水甘油醚，在增强Speier铂催化剂的催化下，在温度为50-90℃，制备环氧封端硅油。所述方法解决了现有工业生产方法中原料烯丙基缩水甘油醚原料双键异构化杂质较多，反应时间较长等问题，明显减少了有机废液和废气的排放。
