Abstract

A catalyst is described for the production of unsaturated aldehydes by means of oxidation with a oxygen-containing gas where an active mass, containing at least the elements Mo, Bi, P and O, as well as Si-containing carrier material, is used in the form of a catalyst body with a certain ratio between the outer surface and the volume and with a defined extent in terms of space, porosity, density, specific surface, breaking strength, abrasion, and gas through-flow capability. Also described is a method of making the catalyst.
