Electrolytic production of alkali metal hypohalite
First Claim
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.

Abstract
A process and an apparatus for producing alkali metal hypohalite by passing an alkali metal brine solution through the anode compartment of an electrolytic cell in which the anode compartment and the cathode compartment are separated by a fluid impervious, anion-permeable membrane, providing an aqueous support catholyte into the cathode compartment, impressing an electric potential across the anode and cathode to evolve halogen at the anode and hydrogen at the cathode and recovering alkali metal hypohalite from the anode compartment.
