Abstract
The saturated hydrocarbons, typically alkanes having from 3 to 12 carbon atoms, e.g., propane, are selectively ammoxidized into .alpha.,.beta.-unsaturated nitriles and olefins, e.g., acrylonitrile and propylene, by reacting such alkanes with ammonia and oxygen, in vapor phase and in the presence of a solid catalyst, such solid catalyst including a catalytically effective amount of an active catalytic phase which comprises molybdenum, oxygen and at least one element selected from among the alkaline earth metals, Mn, Fe, U, La, Co, Ni, Zn, Ag, Cd, W, Zr, Pb, Te, Ga, Al, B, Nb and Ta.
