Abstract

Procedure for the pure preparation of chlorine, hydrogen and alkaline phosphates in concentrated solution, by electrolysis in a cationic permoselective membrane cell, characterized in that, in a cell that comprises a cationic permoselective membrane placed between the two electrodes and whose anode, of porous nature to allow percolation of the electrolyte, it presents electrochemical activity only on the side opposite to the membrane, a solution of alkaline chlorides is introduced into the anode compartment, by forced circulation, while the cathodic compartment arrives, by forced circulation, concentrated phosphoric acid or an alkaline phosphate in concentrated solution.
