PROCESS FOR MAKING DIMETHYL CARBONATE

摘要

An eco-friendly process for making dimethyl carbonate comprising contacting methanol with carbon dioxide in the presence of a solid, calcined catalyst derived from zirconium phosphonate catalyst having molecular formula: Zr(X)2-nYnsmH2O where X refers to phosphonate, Y refers to HPO4 2- or HPO3 2-, n varies from 0.2 to 1.8 and m varies from 0 to 5, is disclosed.
