PURPOSE: To easily obtain the alkali hydroxide which does not by produce chlorine by supplying an aq. soln. of alkali carbonate, etc., into the anode chamber of an electrolytic cell for which an ion exchange membrane is used and effecting an electrolysis by using an electrode formed by coating the surface of Raney nickel with rhodium, platinum, etc., as an anode.
CONSTITUTION: The electrolytic cell segmented with an anode chamber and a cathode chamber by the cation exchange membrane is assembled. The particles of the Raney nickel are stuck onto the electrode core body by a dispersion plating method. The electrode formed by coating the surface of the Raney nickel with the rhodium, rhenium, iridium, ruthenium, platinum, lead, cobalt, manganese and the alloys contg. these elements is disposed as the anode. The aq. soln. mixture formed by mixing alkali carbonate and alkali hydrogencarbonate and adjusting the pH to 8.5 to 11.5 is supplied to the above- mentioned anode chamber and is electrolyzed, by which the alkali hydroxide is obtd.
