Abstract
692,763. Electrolytic production of chlorine dioxide. FARBENFABRIKEN BAYER. Oct. 30, 1951 [Feb. 20, 1951], No. 25392/51. Class 41. Chlorine dioxide, substantially chlorine-free, is obtained by electrolysis of an aqueous solution of a chlorite, e.g. sodium chlorite, in the presence of a water-soluble sulphate. In an example, the anode compartment of a diaphragm cell is charged and subsequently fed at a rate of 25 c.c. per hour by an automatic device with a solution of 200 gms. sodium chlorite and 80 gms. sodium sulphate per litre. Inert gas such as air is introduced by a distributer at the bottom of the anode to remove the chlorine dioxide. The outflowing gas may have a chlorine dioxide content of 3.2-4.1 per cent by volume and a chlorine content of 0.4-0.9 per cent. Caustic soda solution is removed from the cathode compartment through an overflow. The anode may be of platinum and the cathode of lead. The anode chamber is provided with cooling means. A prior process for the production of chlorine dioxide by electrolysis of a chlorite in the presence of a chloride is referred to.
