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.
