    Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.

    Abstract: 1,145,539. Electrolytic cell for producing organic compounds. BADISCHE ANILIN - & SODA - FABRIK A.G. July 8, 1966 [July 9, 1965; Jan.13, 1966], No.30712/66. Heading C7B. Apparatus for performing electro-chemical reactions of organic compounds in a flowing electrolyte, particularly the hydrodimerization of acrylonitrile to adiponitrile, comprises at least one uniformly liquid-permeable electrode pair 1a, b in which the electrodes are spaced less than 1 mm. apart, preferably separated by a liquid-permeable insulator 22, e.g. porous glass fibre cloth or paper, or porous plastic sheeting or ceramics. Electrolyte may be supplied and withdrawn, preferably recycled through a heat exchanger, to enable it to flow through the electrode pair(s). Pulsations may be imparted to the electrolyte and/or the electrode pair(s), e.g. by securing the electrode support and connection 4 to a vibrator 23. Current may be supplied through metal sleeves 2 pressed coaxially into plastic spoked-wheel shaped members 3. The electrodes may be made of metal or wire cloth, screens, expanded metal or sintered articles. Cathodes may be composed of Cu, brass or iron wire coated with Pb, Cd, Hg, Hg-Pb, Pb-Th, Hg-Ag, or Zn, Cu, Pt, Pd, Ni or graphite activated with Pt; anodes may be composed of metal or wire cloth or expanded metal support of Pt, Ni, Ti, or Ta coated with Ni or Pt with a coating of PbO 2 or Tl 2 O 3 , Pt, Pt-Ir, Pt-Rh, Ni, Fe, alloy steel or graphite. For producing adiponitrile with some propionitrile, examples are given of electrolytes composed of 66-81À5% acrylonitrile, 5-15% methanol or 20 or 22À5% isopropanol or 20% dioxane or dimethyl formamide, 7 or 8% water, and 0À5 or 1% tetramethyl ammonium methyl (or p-totuene) sulphate; the pH is regulated by adding acetic acid and triethylamine through a dropping funnel 27, and the off gas pipe passes through a reflux condenser 28. A solution of monomethyl adipate in methanol, electrochemically reacted with sodium methylate, is condensed to dimethyl sebacate. The apparatus may be used for other organic electro-chemical reactions.
