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. |
