The electrochemical synthesis of cyclic carbonates from CO2 with epoxides was carried out in an undivided cell using Al as a sacrificial anode and Bu4NBr/DMF as the electrolyte at room temperature. The influence of some key factors (such as kinds of the electrode materials, supporting electrolyte, CO2 pressure and solvents) on the results of the electrosynthesis was investigated. The cyclic carbonates could be obtained in moderate to high yields of 65~98% in 0.05 mol•L-1 Bu4NBr/DMF electrolyte solution under 4 MPa CO2 with a platinum cathode.
