  Abstract

The synthesis of dimethyl carbonate (DMC) with Cu catalysts was investigated in a semi-batch high-pressure reactor. DMC was synthesized via the direct oxidative carbonylation of carbon monoxide with oxygen in methanol. The corrosion rate was evaluated fro the weight change for SUS test pieces which had been added into the reactor. In order to reduce the corrosion rate without significantly losing DMC yield, various additives such as amines, olefins, and other metal salts were used. When 1-methylimidazole was used as an additive, 18.6% of DMC yield could be obtained without corrosion. If the amount of 1-methylimidazole was decreased, a high DMC yield (33.2%) could be obtained with a low corrosion rate (0.5%).
