Abstract
1487284 Electrolysis in diaphragm cells ASAHI KASEI KOGYO KK 6 March 1975 [9 March 1974 30 Sept 1974 10 Dec 1974] 9388/75 Heading C7B In a process for electrolysis of an aqueous electrolyte solution, e.g. for producing NaOH, Cl 2 and H 2 from saline water, LiOH, KOH, I 2 , Br2, HClO 3 , HBrO 3 , H 2 S 2 O 8 , or adiponitrile from acrylonitrile, in a diaphragm cell having a cation exchange membrane 1 to partition the cell into a cathode and an anode chamber, in which gas is generated at least at the anode 2, the internal pressure in the cathode is kept higher (e.g. 0À2 to 5m water column) than that in the anode chamber to press the membrane towards the anode, e.g. by discharging the gas generated at the anode, (such as Cl 2 ) backwardly of the anode; with gases generated being discharged backwardly of the respective electrodes the cathode chamber is larger in volume than the anode chamber. Preferably gas permeable metallic plates are used as anode and cathode, e.g. expanded, multi-rod, perforated sheet or mesh of noble metal (e.g. Ru with or without Ti) oxide coated Ti for the anode and Ni (alloy or thiocyanate) plated Fe for the cathode. As shown (Fig. 1) the anode 2 may be carried by supports 71 on a partition wall 72 (of explosion-bonded Ti and Fe plates), between the gas-ascending space and downcomer 113, spaced from the partition 111 by distance piece 73 and connected by conductor rod 112. Mineral acid, e.g. HCl, H 2 SO 4 or HNO 3 , may be added to the anolyte to maintain the pH at or below 3À5. Bipolar electrodes may be used Fig. 4 (not shown): anode 2, a Ti plate coated with (mole per cent) 55 RuO 2 -40, TiO 2 -5ZrO 2 , joined to cathode 3, an expanded Fe plate, via Ti and Fe ribs 7, 9 and a partition wall 4 formed by explosion-bonding Ti plate 5 onto Fe plate 6. NaCl and NaOH solutions are charged into anode and cathode chambers 8, 10 via nozzles 13, 15, and Cl 2 and H 2 gases are discharged via nozzles 14, 16. The anolytes and catholytes may be recycled. The cation exchange membrane may be a polymer of perfluorosulphonic acid compound, sulphonated styrene-divinyl benzene, acrylic acid-divinyl benzene, or a phosphoric acid type membrane.
