Abstract

The invention relates to a process for production of an alkaline hydrogen peroxide solution and an acidified alkali metal salt solution containing chlorate in an electrochemical cell including an anode compartment provided with an anode and a cathode compartment provided with an oxygen reducing cathode. In the cathode compartment an aqueous alkali metal hydroxide and hydrogen peroxide is formed, wherein the molar ratio MOH:H.sub.2 O.sub.2 for the net production thereof is maintained from about 0.1:1 to about 2:1. Also a process for simultaneous production of chlorine dioxide is disclosed.
