Abstract
1468942 Electrolytic diaphragm cells HOOKER CHEMICALS & PLASTICS CORP 15 July 1974 [19 July 1973 15 Aug 1973] 31179/74 Heading C7B An electrolytic cell, for electrolyzing aqueous solutions of alkali metal halides e.g. NaCl to produce alkali metal hydroxides and halogen e.g. NaOH and Cl 2 , of HCl to produce H 2 and Cl 2 , of ammonium sulphate to produce persulphate and of borax to produce perborates, comprises a housing 1, an anode compartment 3 and a cathode compartment 7 containing anode 5 and cathode 9 and at least one buffer compartment 11 therebetween, at least the anode compartment and the adjacent buffer compartment being separated from each other by a permselective barrier 13, impervious to liquids and gases and comprising a hydrolyzed copolymer of a perfluorinated hydrocarbon, e.g. tetrafluoroethylene or hexafluoropropylene, and a fluorosulphonated perfluorovinyl ether, e.g. FSO 2 CF 2 CF 2 OCF(CF 3 )CF 2 OCF = CF 2 (as disclosed in Specification 1431733), in which some of the sulphonic acid groups may be replaced or modified, or sulphostyrenated perfluorinated ethylene propylene polymer. All compartments may be separated by the barrier. When at least two buffer compartments are used Figs. 2, 3 (not shown) at least the anode compartment and the adjacent buffer compartment are separated from each other by the permselective barrier and at least the cathode compartment and its adjacent buffer compartment may be separated by a porous diaphragm e.g. of asbestos or polypropylene. Dilute NaOH solution removed for example from the buffer compartment(s) may be introduced into the cathode compartment. The anode may be of RuO 2 coated Ti and the cathode may be of steel.
