IMPROVED PREPARATION METHOD FOR GLYCEROL MONOMETHACRYLATE

摘要

The present invention relates to a method for preparing glycerol monometacrylate through hydration epoxy ring-opening reaction under an acid catalyst by using glycidyl metacrylate as a raw material. The preparation method of the present invention selectively uses a heterogeneous solid acid catalyst of heteropoly acid or sulfateion supported complex metal oxides, thereby preparing glycerol monometacrylate of high purity and yield in a short period of time. Also, the recovery of the catalyst is possible after end of reaction, so problems of treating spent acid and waste water which are issues of existing methods can be solved.;COPYRIGHT KIPO 2015
