Abstract
A process for producing glyoxalic acid which comprises electrolytically oxidizing glyoxal in an electrolytic cell comprising at least one anode, at least one cathode and at least one cation exchange membrane therebetween to define an anode compartment(s) and a cathode compartment(s) therein, using an aqueous solution containing glyoxal and halogen ions as an anolyte solution and an aqueous solution containing an inorganic or organic electrolyte as a catholyte solution.
