Abstract
PURPOSE: To obtain an alkali hydroxide by raising the durability of cathode and using high current efficiency and low voltage by carrying out electrolysis while diffusing a fixed amount of air into the hole of porous cathode containing catalyst and hydrophobic substance.
CONSTITUTION: In the manufacture of a caustic alkali by electrolyzing an alkali chloride aqueous solution in the electrolytic bath 1 consisting of the cation exchange membrane 2, the cathode 6, and the anode 3, the porous cathode 6, having an average fine pore diameter of 0.01W50μ, a porosity of 30W80%, and an air passing coefficiency of 1×10-5W1×10-1 mol/cm2.cmHg, is used, and electrolysis is carried out while diffusing air of 10.54 1/amp.hr or more per pair of cathode and anode into the hole of the cathode through the inlet 12 and the supply chamber 7. Thus, an alkali hydroxide can be obtained at a high current density and a low voltage and at the same time the durability of the cathode can be raised.
