    Abstract: Manufacture of saturated aliphatic alcohols by hydrogenation of saturated aliphatic aldehydes at temperatures of from 140* to 230*C at pressures of from 50 to 350 atmospheres in the presence of catalysts containing from 5 to 15% by weight nickel and 5 to 20% by weight molybdenum supported on silicic acid, in which process catalysts are used which have been obtained by heating silicic acid carrier materials to temperatures of from 700* to 1200*C, impregnating the resulting silicic acid carrier materials with nickel and molybdenum salts, drying the resulting material with or without further heating to temperatures of from 200* to 500*C and subsequently treating the product with hydrogen at elevated temperature in conventional manner. The alcohols obtained are used as solvents or for the manufacture of plasticizers for polyvinyl chloride.

    Abstract: A process for the production of mainly linear aldehydes by hydroformylation of an olefinically unsaturated compound of from two to twenty carbon atoms with carbon monoxide and hydrogen at elevated temperature and superatmospheric pressure in the presence of a cobalt carbonyl complex prepared prior to the hydroformylation from an aqueous solution of a cobalt salt, wherein in a first stage an aqueous solution of a cobalt salt is treated with carbon monoxide and hydrogen at a temperature of from 50* to 200*C and at a pressure of from 100 to 400 atmospheres in the presence of activated carbon, a zeolite or a basic ion exchanger which has been loaded with cobalt carbonyl, the aqueous solution containing cobalt salt and cobalt carbonyl hydride thus obtained and the mixture of carbon monoxide and hydrogen, without releasing the pressure, are extracted at a temperature of 20* to 100*C and at a pressure of 100 to 400 atmospheres in a second stage with a saturated hydrocarbon or the olefinically unsaturated compound used for the hydroformylation (provided they are insoluble in water and liquid under the conditions used), water-insoluble oxo reaction product or hydrogenated oxo reaction product, the aqueous phase is separated and the organic phase containing the carbonyl complex thus obtained and the mixture of carbon monoxide and hydrogen are transferred to a third stage and, after supplying olefinically unsaturated compound (if this has not been used or has only partly been used for extraction in the abovementioned stage) hydroformylation is carried out at a temperature of from 70* to 170*C and a pressure of from 100 to 400 atmospheres. The products of the process are suitable for the production of detergent alcohols and plasticizers and for the production of carboxylic acids and amines.
