Abstract:
     A direct synthesis process for preparing dimethyl carbonate includes reaction of magnesium on methanol with magnesium at 3-9% of methanol at 200 deg.C for 1 hr to generate magnesium formate and gas-liquid reaction of CO2 under a pressure of 10-50 kg/cm2 on methanol at 120-200 deg.C for 1-11 hr to generate dimethyl carbonate, and features simple technology and no secondary environmental pollution.
