Abstract

1480538 Diaphragm electrolysis of alkali metal halides DIAMOND SHAMROCK CORP 3 Feb 1975 [4 Feb 1974] 4585/75 Heading C7B The electrolysis is conducted in a cell wherein the anode and cathode are separated by a single upright hydraulically impervious cationic membrane positioned nearer the anode than the cathode. This is achieved either using pressure to flex a thin membrane towards the anode as by adjustment of the liquid heads or application of a gas-pressure or vacuum, or using spacers on the electrodes. Conventional membrances based on e.g. divinyl benzene/acrylic acid polymer, polyethylene, poly (divinylbenzene-styrene) or polyvinylfluorocarbons, having sulphonic, phosphonic or carboxylic groups and containing 15-40% gel water are specified. The membrane may be on the anode. Significant reductions in operating voltage are achieved. Conventional anodes and cathodes are specified.
