ABSTRACT:
Disclosed is a method of making a catalyst precursor by reacting the ion VO(O.sub.2).sup.+ in aqueous solution with an antimony compound that contains Sb having a valence of 3. In one embodiment, the VO(O.sub.2).sup.+ ion is made by reacting H.sub.2 O.sub.2 with a vanadium compound.
Also disclosed is making a catalyst by drying and calcining such precursor. When the drying is effected by spray drying a new microspheroidal catalyst is produced. The catalysts useful for ammoxidation of propane are more attrition resistant than catalysts of the same empirical formula made by prior art methods.
