Abstract: Dimethyl carbonate (DMC) was synthesized using supercritical CO2-feeding methanol (MeOH) and dimethyl ether (DME). Along with increasing temperature, the yield of DMC was changed. At 130°C, a maximum yield of 28.58% was obtained. The main problem for the synthesis of DMC was the removal of product water. When the amount of DME was excess, the concentrations of CO2 and MeOH would be diluted so that the reaction rate of CO2 + 2MeOH = DMC + H2O would be decreased. If the amount of DME was too few, the hydrolysis reaction H2O +DME = 2MeOH would not be successful. Besides DMC, the by-products present in reaction mixture were methycarbamate and other unknown substances.
