摘要

Electrochemical carbonylations of ethanol, methanol and ethylene were studied at the Pd/C anode with NaClC>4 electrolyte. The carbonylation of ethanol to diethyl carbonate (DEC) efficiently proceeded with a current efficiency of 50% as well as the carbonylation of methanol to dimethyl carbonate (DMC). Cross-carbonylations of ethanol and methanol to ethyl methyl carbonate (EMC) and of ethylene and methanol to methyl 3-methoxy-propionate and dimethyl succinate proceeded at the Pd/C anode. These facts indicated the formation of an alkoxycarbonyl intermediate on the Pd/C anode during the carbonylation.
