ABSTRACT:
Disclosed is a process for making an activated antimony and vanadium-containing catalyst in oxide form having an atomic ratio of Sb:V in the range from 0.8-4, which comprises calcining such an oxidic vanadium and antimony-containing composition at a temperature of over 750.degree. C., and thereafter contacting said calcined catalyst with a hydroxy compound in liquid form selected from (1) cyclohexanol, (2) cyclopentanol, (3) a monohydroxy, acyclic hydrocarbon having 1-8 C atoms, and (4) a dihydroxy, acyclic hydrocarbon having 2-4 carbon atoms, and separating as a liquid said compound from said catalyst insofar as it is present beyond the amount wetting said catalyst, and thereafter drying said catalyst.
