Synthesis of dimethyl carbonate from carbon dioxide and methanol

摘要

A method for producing dimethyl carbonate from methanol and carbon dioxide using a heterogeneous catalyst is described. The heterogeneous catalyst provides both acidic sites and basic sites. The reaction can be carried out at atmospheric pressure and relatively low temperatures.
