| titleOfInvention | Electrolytic production of hypochlorite compositions |
| abstract | 1417949 Anode for producing hypochlorite DIAMOND SHAMROCK CORP 18 April 1974 [19 April 1973] 17106/74 Heading C7B Alkali metal hypochlorite is produced e.g. for sewage treatment by electrolyzing an alkali metal chloride solution e.g. sea water between a cathode, e.g. of Ti, steel or Ti bearing a mixed TiO 2 -RuO 2 coating, and an anode comprising a conductive base, e.g. of Ti, Ta, Nb, Zr substrate or coating over Cu or Al, bearing on at least part of its surface a coating comprising 30 to 90% SnO 2 , 1 to 10%Sb 2 O 3 , 1 to 50% at least one Pt group metal oxide preferably RuO 2 +IrO 2 or RhO 2 and 0.5 to 30% TiO 2 or Ta 2 O 3 , the mole ratio of SnO 2 : Sb 2 O 3 being from 85:15 to 95:5. The mixed metal oxide coating may be produced by painting or brushing with an acidified alcoholic solution of the appropriate thermochemically decomposable salts, e.g. chlorides, nitrates, alkoxides, alkoxy halides, resinates or amines, followed by drying and baking in air. Examples are K 2 PtCl 6 , H 2 IrCl 6 , RuCl 3 or RuBr3, orthobutyl titanate, SbCl 3 or SbCl 5 , SnCl 4 or dibutyl SnCl 2 dissolved in butanol (with HCl). Intermediate layers as described in U.S.A. Patent 3711397 may be present. The anode substrate may be imperforate or foraminous, e.g. an expanded Ti sheet. The cell is preferably diaphragmless with bi-polar electrodes. The solution may be recirculated. Specification 1417950 is referred to. |
