    Abstract: Alcohols are prepared from carboxylic acids by catalytic hydrogenation at an elevated temperature in the presence of a cobalt catalyst which contains copper, manganese and/or chromium. Inorganic acids which can form polyacids and/or an alkali metal, alkaline earth metal or earth metal salts thereof, e.g. sulphuric, boric, phosphoric, molybdic, vanadic and tungstic acids may also be present. The catalysts may be supported, e.g. on silicic acid, bauxite, fuller's earth or aluminium oxide, or unsupported. Examples describe the hydrogenation of propionic, butyric, lauric, oleic, suberic, azelaic, and sebacic acids, decane dicarboxylic acid-(1-12) benzoic, hexahydrobenzoic, phenylacetic, and salicylic acids and a mixture containing succinic glutaric, adipic, e -hydroxycaproic, butyric, valeric and caproic acids obtained as by-product in the catalytic oxidation of cyclohexane with air.

    Abstract: Aliphatic dinitriles containing 4-22 carbon atoms, having at least 2 carbon atoms between the nitrile groups, and having, apart from the nitrile groups, a hydrocarbon structure, are purified by bringing them in the presence of water into contact with an alkali metal bisulphate, ammonium bisulphate, an ammonium bisulphate N-substituted by 1-3 alkyl groups having 1-4 carbon atoms, or a bisulphate of a divalent metal which does not form a sulphate which is difficulty soluble in water, e.g. iron, manganese, zinc, cobalt and nickel. The amount of water is preferably 3-8% by weight of dinitrile, and the amount of bisulphate preferably 0.01-10% by weight of dinitrile. Specified dinitriles are adipodinitrile, suberodinitrile, sebacodinitrile and the mixture of 1.9- and 1,10-dicyanoheptadecane known as heptadecane dicarboxylic acid dinitrile. The temperature may be from the solidification point of the dinitrile to 200 DEG C. or more. The purified dinitriles may be reduced to the corresponding diamines.

    Abstract: Soaps, synthetic detergents and mixtures thereof in solid form, e.g. in cake, flake, needle and powder form, are stabilized against spotting and rancidity caused by heavy metal ions such as those of iron, nickel and copper by the incorporation of an additive which is substantially free from uncombined alkali metal hydroxide comprising (a) one or more polyhydric alcohols containing more than 4 hydroxyl groups, and (b) one or more complex-forming compounds containing the group where R1 and R2 each represent -C2H4OH or -CH2COOX, X being hydrogen or an alkali metal. The total of (a) and (b) preferably amounts to 0.05-5% by weight of the composition, and the weight ratio of (a) to (b) is 2:1 to 1:1. (a) is for example manitol, xylitol, or hydrogenated wood hydrolysate, but is preferably sorbitol, while (b) may be dihydroxyethylamino-acetic acid, iminodiacetic acid, nitrilotriacetic acid, hydroxyethylethylene diamine triacetic acid, ethylene diamine triacetic acid, 1:2-diaminocyclohexane tetracetic acid, N:N1-dihydroxyethyl-1:2-diaminocyclohexane-N:N1 -diacetic acid, 2-hydroxy-1:3-diaminopropane tetracetic acid, or tetrahydroxyethyl-1:2-diaminocyclohexane, but is preferably ethylenediamine tetracetic acid. Suitable detergents, in addition to soap, include alkyl sulphates or sulphonates, alkylglycol ether sulphates, alkylaryl sulphonates, fatty acid condensates, poly-glycol ethers of alkylphenols or fatty alcohols, or cationic active compounds. Cellulose ether carboxylic acids, cellulose ethers and esters, salts of polyacrylic and polymethacrylic acids, polyvinyl compounds such as polyvinylpyrrolidone, polyglycol ethers, fatty acid alkanolamides, triethanolamine, esters of polyhydric alcohols and glucosides, glucosides themselves and ethylene condensates of such esters and glucosides, potato flour, phosphates, silicates, sodium chloride and sulphate, talc, bentonite, titanium dioxide, paraffin wax, petroleum jelly, skin protectives, disinfectants, optical brighteners and dyestuffs may also be incorporated.

    Abstract: 1,129,280. Hexamethylene oxide. BADISCHE ANILIN- & SODA-FABRIK A.G. 16 Nov., 1966 [17 Nov., 1965], No. 51329/66. Heading C2C. Hexamethylene oxide is obtained by dehydration of a reaction mixture containing hexanediol-(1,6) and 20-80% by weight of water based on the mixture at elevated temperature in the presence of solid dehydration catalysts. The catalyst used should be non- alkaline, e.g. aluminium oxide/boric acid, aluminium phosphate, aluminium phosphate/copper chromite and aluminium phosphate/chromium. The temperature range normally used is 160- 400‹ C. α-Methyltetrahydropyran is also obtained in some examples.
