Abstract: A process is disclosed for preparing aliphatic .alpha.,.omega.-aminonitriles by partially hydrogenating aliphatic .alpha.,.omega.-dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The process is characterised in that the catalyst is obtained by thermally decomposing a metal compound selected in the group made up of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones until the corresponding metal and/or a metal oxide thereof is obtained, provided that the metal used be nickel or cobalt.

Abstract: Ketones of the general formula (I) (I) where R1 and R2 independently of one another are each alkyl, cycyloalkyl, arylalkyl, aryl or hetaryl, and one or more of the radicals R1 and R2 carry one or more hydrogen atoms on the .alpha.-carbon atom, are prepared by reacting two carboxylic acids of the general formulae (IIa/IIb), R1-COOH (IIa) and R2-COOH (IIb) or by reacting carbocylic acid R1-COOH (IIa) and a ketone (Ib) or by reacting a mixture of IIa, IIb and Ib, in the gas phase in the presence of a catalyst, by a process in which a catalyst is used whose active material contains at least 50% by weight of titanium dioxide having a specific surface area greater than 10 m2/g.O
