    摘要: A vanadium/phosphorus oxide oxidation catalyst suitable for catalytic oxidation of C.sub.4 feed stock in the preparation of maleic anhydride is formed by calcining an intercalation complex of the formula VOHPO.sub.4 .multidot.0.5H.sub.2 O.multidot.({C.sub.n H.sub.2n+1 }--X).sub.z in which n has a value of from 0 to 20, z has a value of from about 1.5 to about 1.9; and X is an oxygen- or nitrogen-containing functional group operable to form hydrogen bonds with the structural P--OH and water groups of the complex.
