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.
