    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: Water-insoluble pigments are continuously finely dispersed in fibre-forming polymers by grinding the pigment in a sand mill or bead mill, passing the dye suspension leaving the mill into a mixing unit in which it is mixed with the molten intermediates for the polymer, then passing the mixture into a reactor at 250-300 DEG C. for polymerization or polycondensation. Suitable pigments are TiO2, Fe2O3, MgO, CaCO3, BaSO4 and the phthalocyanines. These are preferably suspended in water, or when for use with polyethylene terephthalate, in glycol. The suspension may contain 7-25 wt. per cent of pigment. Materials to be pigmented may be polyamides and polyesters deriving from e.g. caprolactam, laurolactam, capryllactam or from dimethyl terephthalate and ethylene glycol, or the monomeric transesterification product thereof. The mill may be heated up to 250 DEG C. Suitable apparatus comprises a sand or bead mill with an inlet at the bottom, and an outlet at the top leading to a closed, heatable, cylindrical mixing unit, from which an outlet leads to a polymerization vessel. In examples TiO2 is suspended in water containing sodium metaphosphate or in ethylene glycol containing alumina sol and mixed with caprolactam or an ethylene glycol/dimethyl terephthalate mixture respectively.
