摘要：A method for purifying a dipeptide ester by electrolysis in an electrolytic cell comprising an anode compartment, a cathode compartment and a central compartment partitioned by ion exchange membranes, which comprises supplying an aqueous dipeptide ester solution containing organic acids to the central compartment defined by anion and cation exchange membranes or by anion exchange membranes and an aqueous electrolyte solution to the cathode and anode compartments, and electrically removing the organic acids from the central compartment to the anode compartment through the anion exchange membrane.
