Improved process for preparing glycerol monomethacrylate

摘要

invention is glycidyl methacrylate as a raw material by using an acid catalyst under the hydration epoxy ring-opening reaction by a method for manufacturing a glycerol monomethacrylate. In the process of the present invention can be prepared by using selected the heterogeneous solid acid catalyst of a heteropoly acid or sulfate ion is supported mixed metal oxide as an acid catalyst in a short reaction time, high purity and yield, glycerol monomethacrylate, and the reaction After completion it is possible to solve the problem of waste water treatment in question was or spent acid can be recovered by conventional methods of catalyst.
