Abstract: 1298814 Electro-dialysis ASAHI KASEI KOGYO K K 12 Dec 1969 [15 Dec 1968] 60783/69 Heading C7B [Also in Divisions B1 and C2] A solution containing both HNO 3  and metal ions (e.g. Cu and V) is electro-dialytically recovered from an acidic waste liquor. The waste liquor is produced in the liquid phase oxidation of cyclohexanone or cyclohexanol with an aqueous solution of HNO 3  in the presence of a metal oxide catalyst to form adipic acid. The electro-dialysis apparatus employs, as recovering liquid, water or dilute aqueous HNO 3 . The acidic waste liquor, before being electro-dialyzed may be subjected to diffusion dialysis. The waste liquor and recovered liquid obtained from the diffusion dialyzer may be used as the acidic waste liquor and the recovering liquid for the electrodialysis. Fig. 1 illustrates electro-dialysis using six electro-dialyzers 1-6 fastened together. Waste mother liquor 17 from the oxidation process is fed through the electrodialyzers in series and is removed as final waste at 21. Recovering liquid 24 is also fed through the electro-dialyzers in series but in countercurrent to the mother liquor and spaced therefrom by ion-exchange membranes. Concentrated recovered liquid may be further concentrated by evaporation and is returned to the oxidation process at 26. H 2 SO 4  is circulated to the electrode chamber of the electro-dialyzers from a reservoir 14. Different current densities can be used in the electro-dialyzers to take account of the different concentrations of the solutions employed therein. The cation exchange membranes for the electrodialyzers may have been prepared by sulphonating a styrene/butadiene/divinylbenzene copolymer with sulphuric anhydride. The anion exchange membranes may have been prepared by treating the same copolymer with dichloroethane and subsequently with triethylamine. Specified membranes for diffusion dialyzers are of parchment paper.
