Abstract

A process for producing geometric shaped catalyst bodies K whose active material is a multielement oxide of stoichiometry[Bi1WbOx]a[Mo12Z1cZ2dFeeZ3fZ4gZ5nOy]1,in which a finely divided oxide Bi1WbOx with the particle size d50A1 and, formed from element sources, a finely divided intimate mixture of stoichiometry Mo12Z1cZ2dFeeZ3fZ4gZ5h with the particle size d50A2 are mixed in a ratio of a:1, this mixture is used to form shaped bodies and these are treated thermally, where (d50A1)0.7·(d90A1)1.5·(a)−1≧820.
