Title: Electrolytic treatment of waste sulfate pickle liquor
IPC: C25C1/06
Filed: 1955-11-07
Abstract: 794,368. Electrodialysis. ROHM & HAAS CO. Nov. 7, 1955 [Nov. 9, 1954], No. 31754/55. Class 41. A process for regenerating spent iron pickle liquor containing dissolved ferrous sulphate and sulphuric acid comprises employing the liquor as catholyte in a cell 1 divided by an anionic permselective membrane 2 into a cathode compartment 5 and an anode compartment 6 which contains an aqueous electrolyte, e.g. a solution of sulphuric acid, as anolyte, a direct electric current being passed through the cell to deposit metallic iron on the cathode 3 and to form sulphuric acid in the compartment 6. Sulphate ions migrate to the anode 4 where oxygen is given off to escape at 8, the concentration of hydrogen ions increasing in the anolyte to concentrate the acid there. Simultaneously, hydrogen is given off at the cathode 3 to raise the pH of the catholyte, until at a pH of 1.8 iron starts to be deposited on the cathode 3. The anolyte and catholyte may circulate through their respective compartments by pipes 10, 12 and 11, 13, and to overcome back migration of hydrogen ions as the conductivities of the anolyte and catholyte diverge during operation, the pipes 12, 13 may be joined by a hose to refurnish the anolyte with dilute sulphuric acid, the concentrated anolyte being drawn off at 11, e.g. for re-use as a pickling solution. In a modification, liquid is directed from the pipe 12 upwardly through a central compartment formed between two anionic membranes, from which it is delivered to the bottom of the anode compartment as before. Flow of liquid may be ensured by pumps or by arranging the inlet 10 above the outlet 11. By the process, the concentration of ferrous sulphate in the liquor is reduced to 1 to 5 per cent. Cooling coils may be disposed in the compartments to maintain the temperature at 60‹ to 95‹ C., and to cathode current density should be 50 to 150 amps per square foot, e.g. 90. The anode 4 should be platinum, lead or lead alloy, e.g. antimonial lead, the cathodes of iron, steel, stainless steel, aluminium, titanium, nickel or graphite, and the vessel 1 may be of hard rubber, phenolformaldehyde resin or polymethyl methacrylate. The diaphragm 2 contains an anion-exchange resin, being e.g. constructed as described in Specification 721,160, [Group IV (a)]. Concentrations of the constituents of the anolyte and catholyte before and after operation are given and also flow rates. Voltages of 4 to 6 are mentioned and it is stated that the cell could operate at super atmospheric pressure.

Patent GB-645067-A (GB)
Title: Improvements in or relating to the production of polymeric compounds
IPC: C08F16/12
Filed: 1947-12-09
Abstract: Vinyl allyl ether is polymerized in solution, e.g. in benzene, at a temperature below 38 DEG  C. in the presence of a catalyst selected from iodine, halides of metals or metalloids, e.g. aluminium, stannic or ferric chlorides, boron fluoride or boron fluoride-ether complexes, to yield organic solvent-soluble, viscous to rubbery products containing unsaturated allyl linkages. Polymerization may be stopped at this stage by removing or destroying the catalyst, e.g. by addition of aqueous potassium carbonate, or by avoiding excessive rise in temperature.  Further polymerization results in insoluble, hard, transparent products. The unsaturated polymer combines with oxygen from the air and may be used as a paint ingredient, either alone or with a solvent, plasticizer, e.g. dibutyl phthalate, tri-cresyl phosphate and castor oil, siccative, e.g. cobalt resinate or naphthenate, and pigments.  It may be heated in the absence of air, if desired using benzoyl peroxide, aluminium chloride or boron fluoride as catalyst, to form a hard insoluble product.  It may also be vulcanized by heating with sulphur or sulphur and piperidine. Specifications 540,938 and 540,940, [both in Group IV], are referred to.
