Abstract

Improvements introduced in a procedure for the electrolysis of aqueous solutions of alkali metal halides in an electrolytic cell provided with an anode and a cathode separated by a permoselective cation membrane, electrolytically conductive and hydraulically impermeable, characterized by such improvements that they consist of carrying out the electrolysis with said membrane placed closer to the anode than to the cathode.
