Abstract: In a process for preparing a multiplephase multimetal oxide composition comprising Mo, V, Cu and, if desired, further elements, at least one phase is preformed separately and dispersed in a plastically deformable precursor composition of a further phase. The mixture is dried and calcined. The multimetal oxide composition is suitable as active composition of catalysts for the catalytically oxidation of organic compounds in the gas phase, in particular for the oxidation of acrolein to acrylic acid.

Abstract: A method for the production of acrylic acid (I) by heterogeneous catalyzed partial oxidation of 3C hydrocarbon precursor compound(s) (II) is claimed, where the overall selectivity for by-product formation is 1.5 mol.% of less (especially 0.8 mol. % or less).
