Electrolysis of salt solution
Abstract
Abstract AN AQUEOUS SOLUTION OF ALKALI METAL HALIDE OR HYDROCHLORIC ACID IS ELECTROLYZED IN AN ELECTROLYTIC CELL CONSISTING OF AT LEAST ONE UNIT CELL WHICH COMPRISES A CATHODE, AN ANODE, A CATION EXCHANGE MEMBRANE, AND A NEUTRAL DIAPHRAGM HAVING A WATER PERMEABILITY OF NOT MORE THAN 5 CC/MIN. CM.2 UNDER A PRESSURE DIFFERENCE OF 1 KG./CM.2, WHERE THE CATION EXCHANGE MEMBRANE AND THE NEUTRAL DIAPHRAGM ARE JUXTAPOSED AT A DISTANCE BETWEEN THE CATHODE AND THE ANODE TO FORM AN ANODE COMPARMENT BETWEEN THE ANODE AND THE NEUTRAL DIAPHRAGM, AN INTERMEDIATE COMPARTMENT BETWEEN THE NEUTRAL DIAPHRAGM AND THE CATION EXCHANGE MEMBRANE, AND A CATHODE COMPARTMENT BETWEEN THE CATION EXCHANGE MEMBRANE AND THE CATHODE, BY PASSING EACH COMPARTMENT SOLUTION AT A FLOW VELOCITY OF AT LEAST 3 CM./SEC., WHILE KEEPING AN INSIDE PRESSURE OF THE INTERMEDIATE COMPARTMENT HIGHER THAN THAT OF THE ANODE COMPARTMENT.
