Effect of Temperature on the Dimethyl Carbonate Synthesis Yield from MethylCarbamate and Methanol Catalyzed by Zinc Acetate

In this study, zinc acetate was used as catalyst for the synthesis of dimethyl carbonate (DMC)through the reaction between methyl carbamate (MC) and methanol (urea alcoholysis process). The effect ofthe temperature on the DMC yield was investigated in batch catalytic mode. It was uncovered that the DMCyield increased with increasing the temperature; however, the moderate temperature (۱۶۵ °C) was selectedas the optimal temperature because the undesired byproduct (NMMC) was at the lowest level while the DMCproduction yield remained also high enough.
