Abstract
Process/apparatus for electrolytically oxidizing solutions of ionic compounds features the electrolytic oxidation of such solutions in a first anode compartment of an electrolytic cell, said electrolytic cell further comprising a second anode compartment, a cathode compartment, and a pair of cationic membranes respectively separating said cathode compartment from said first and second anode compartments; transferring a portion of said solution electrolytically oxidized in said first anode compartment to said second anode compartment and there continuing the electrolytic oxidation thereof; and then recovering product of electrolytic oxidation from said second anode compartment.
