The present invention is the stoichiometry of the active material A method for producing a geometric catalyst molded body K which is a multi-element oxide of. The method forms a particulate mixture of particulate oxides Bi a Z 1 b O x and stoichiometric Bi c Mo 12 Fe d Z 2 e Z 3 f Z 4 g Z 5 h Z 6 i from an elemental source, said mixture Is mixed by a ratio of p: 1, and a mixture is formed using this mixture, which is subjected to a heat treatment, where c is greater than 0 and not more than 0.8. |
