Open the CIPO recordAbstract From the Canadian patent
Electrolysis of an alkali metal chloride solution is carried out in a cell having the anode and the cathode surfaces in contact with the surfaces of an, ion exchange membrane. The electrolysis is performed at a lower voltage than in, conventional cells and the alkali metal chloride contact of the alkali hydroxide, product is markedly reduced. In the case of a finger type cell alkali metal, chloride impurity in the cell liquor is lowered particularly effectively by maintaining the ratio of the effective area of ration exchange membrane to that of, the anode at 1.1 or less. The invention enables the widely-used asbestos or modified asbestos diaphragms in electrolytic cells to be replaced …
