Properties and applications of electrodes covered with a porous diaphragm—2. Theoretical and practical aspects of electrosynthesis in single compartment electrolysis cells

The use of porous coverings on the counterelectrode for the reduction of the rate of loss reactions in single compartment electrolytic reactors has been studied. The theoretical current efficiencies for various overall reaction schemes have been calculated. The method has been tested for the electrosynthesis of potassium permanganate, ceric sulphate and sodium hypochlorite. Considerably improved reactor performance was realised. The experimental performance was in accord with that calculated theoretically.
