Abstract
Vanadium antimony oxide catalysts useful for the selective oxidation and ammoxidation of paraffins, olefins, and aromatic compounds are manufactured in a process comprising (i) forming a catalyst precursor slurry comprising a vanadium containing compound and an antimony containing compound in a liquid solvent medium which comprises an organic solvent, and (ii) recovering a vanadium antimony oxide from the slurry by drying the slurry in order to remove water and organic solvent.
