Abstract: Preparation of at least one partial oxidation and/or ammoxidation product of propylene involves subjecting crude propylene (prepared by dehydrogenation or oxydehydrogenation in the presence and/or absence of oxygen) in the presence of unconverted propane as a constituent of a gas mixture 2 which comprises a total 4C-hydrocarbon content of at most 3 vol.%, to a heterogeneously catalyzed gas phase partial oxidation and/or ammoxidation. Preparation of at least one partial oxidation and/or ammoxidation product of propylene involves: (a) subjecting crude propane in the presence of and/or absence of oxygen to a homogeneously and/or a heterogeneously catalyzed dehydrogenation and/or oxydehydrogenation to obtain a propane- and propylene-containing gas mixture 1; (b) optionally removing and/or converting to other compounds a portion of the constituents other than propane and propylene contained in the gas mixture 1 to obtain a gas mixture 1' comprising propane and propylene and also compounds other than oxygen, propane and propylene; and (c) subjecting gas mixture 1 and/or gas mixture 1' as a constituent of a gas mixture 2 to a heterogeneously catalyzed gas phase partial oxidation and/or partial gas phase ammoxidation of propylene contained in gas mixture 1 and/or 1'. The total content of 4C-hydrocarbons of gas mixture 2 is at most 3 vol.%.
