    Abstract: Catalysts comprising the combined oxides of vanadium and at least one element selected from the group consisting of boron, niobium, tantalum, antimony, tungsten and chromium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene, or a mixture thereof with molecular oxygen in the vapor phase to yield maleic anhydride. The catalysts of the present invention may be further promoted with additional elements to enhance activity, stability and selectivity. The reaction with n-butane gives an especially pure product in good yield and selectivity.

    Abstract: By the method C3 to C5 monoolefines are amoxydated to theproduction of a,6-monononsaturated acrylonitriles having 3 to 5carbon atoms and HCN by the introduction of monoolefines,molecular oxygen and ammonia in a reaction zone in steam phasecontact with solid amoxydation catalyst. The mole ratio of themolecular oxygen and ammonia introduced was at least 1.5 and 1.0,respectively. The catalyst contains the elements included in theformulaV1SbaMnNnOxwhere a has the value from 0.5 to 2, M is one or more of theelements Sn, Ti, Fe and Ga, m takes the values 0.05 to 3,especially from 0.1 to 1; N means one more of the elements W, Bi,Mo, Li, Mg, P, Zn, Mn, Te, Ge, Nb, Zr, Cr, Al, Cu, Ce, B; n hasthe value 0-0.5. The catalyst is produced by the contact betweenvanadium and antimony compound in water dispersion, the vanadiumbeing in solution.
