Abstract: Process for the preparation of ketones of the general formula I in which R and R independently of one another denote alkyl, cycloalkyl, arylalkyl, aryl or hetaryl, where at least one of the radicals R or R have attached to the alpha carbon atom at least one hydrogen atom, by reacting two carboxylic acids of the general formulae (IIa/IIb), R -COOH (IIa) and R -COOH (IIb) in the gas phase in the presence of a catalyst, the catalysts having an active component of titanium dioxide whose specific surface area is greater than 10 m /g.

Abstract: The application relates to a process for the preparation of a copper-containing catalyst for low temperature conversion which, in addition to copper oxide, contains zinc oxide and aluminium oxide as essential components, by precipitation of the water-soluble salts from aqueous solution in an alkaline precipitant at pH 5.5 to 7.5 and a temperature of 30 to 90@C. After completion of the formation of precipitate, the precipitation product is aged or conditioned, the precipitate is separated off from the reaction solvent, dried and subjected to a temperature treatment and the resulting solid is mixed with a tabletting aid and tabletted to form catalyst mouldings.

Abstract: Catalyst suitable for hydrogenation of organic cpds., comprises (all based on total wt. of catalyst); (a) 80 wt.% nickel (calculated as nickel oxide); (b) 10-25 wt.% of silicon (calculated as zirconium oxide; and (d) 0-10 wt.% of aluminium (calculated as aluminium oxide). The amt. of silicon dioxide and aluminium oxide is at least 15 wt.%. The catalyst is prepd. by; (2) adding an acidic aq. soln. of nickel-, zirconium- and opt. aluminium salts to a basic aq. soln. or suspension of silicon cpds. (and opt. aluminium cpds.), so that the pH of the resulting mixt. drops to at least 6.5; (2) adding a further basic soln. to bring the pH to 7-8; and (3) isolating the pptd. solid, which is then dried, formed and calcined.
