1. An electrolytic process for producing an alkali metal hypohalite solution comprising passing an aqueous alkali metal halide solution through the anode compartment of an electrolysis cell having an anode compartment and a cathode compartment separated by a fluid-impervious anion-permeable membrane with an anode in the anode compartment and a cathode in the cathode compartment, providing an aqueous support catholyte in the cathode compartment, applying an electric potential across the cell sufficient to evolve halogen at the anode and reduce water at the cathode and recovering an effluent solution from the anode compartment containing alkali metal hypohalite.
