ABSTRACT:
A method of preparing a V.sub.a Sb.sub.b M.sub.m N.sub.n O.sub.x catalyst useful in the ammoxidation of a C.sub.2 -C.sub.5 hydrocarbon to its corresponding .alpha., .beta. unsaturated nitrile comprising heating an aqueous mixture comprising V.sub.2 O.sub.5 and Sb.sub.2 O.sub.3 at a temperature above about 100.degree. to 250.degree. C., preferably 110.degree. to 175.degree. C., most preferably 120.degree. to 160.degree. C., under autogenous pressure with agitation to form a catalyst precursor, drying the catalyst precursor and calcining the catalyst precursor to form the finished catalyst.
