Abstract: A process for the preparation of carbonyl compounds by oxidation of alcohols in the gas phase with a gas containing oxygen in the presence of catalysts containing copper or silver and a phosphorus compound that is volatile under the conditions of the reaction, the ratio of the mass of phosphorus to the mass of the alcohol being less than 0.5 ppm.

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.
