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: Process for the purification of aqueous glyoxal solutions which contain acids, by treatment with a solution which contains 20 to 60% by weight of a tertiary amine and 80 to 40% by weight of an alcohol which is not miscible with water at any desired ratio, the treatment being carried out by mixing the two solutions at residence times of less than 5 minutes.
