Title:
METHOD FOR OPERATING ALKALI CHLORIDE ELECTROLYTIC CELL PROVIDED WITH AIR ELECTRODE AS CATHODE
Document Type and Number:
Japanese Patent JPS60221595
Kind Code:
A
Abstract:
PURPOSE:To prevent the deterioration of an air electrode in an alkali chloride electrolytic cell by reducing the concn. of an aqueous alkali hydroxide soln. as a catholyte or replacing the soln. with water when the operation of the electrolytic cell is suspended. CONSTITUTION:When the operation of the alkali chloride electrolytic cell provided with the air electrode as a cathode 1 is suspended, the catholyte 8 is replaced with water by drawing out the catholyte 8 from an outlet 9 for descharging a produced aqueous sodium hydroxide soln. and by feeding water from an inlet 7 for feeding water. Part of the catholyte 8 may be replaced with water. By this method the deterioration of the air electrode 1 is prevented.
