Abstract: An industrial process for the heterogeneously catalytic gas-phase oxidation of propane with molecular oxygen to form acroleine in which, starting with a molar reactant ratio of the propane to the O2 in the undiluted state in the gas mixture fed in of 7:3, said gas mixture is diluted with the reactant propane and possibly inert gases so that the gas mixture fed in has more than 70 vol % propane and at least 5 vol % O2.
