Abstract:
1. A process for the ammoxidation of a saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon to produce an unsaturated nitrile, said process comprising contacting the saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon with ammonia and an oxygen-containing gas in the presence of a catalyst composition comprising a mixed oxide of empirical formula: wherein X is selected from the group consisting of Ti, Sn, Ge, Zr, Hf, and mixtures thereof; L is selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and mixtures thereof; 0.1<a<0.8, 0.01<b<0.6, 0.001<c<0.3, 0.001<d<0.04, 0≦e<0.6, 0≦f<0.1; and n is the number of oxygen atoms required to satisfy valance requirements of all other elements present in the mixed oxide with the proviso that one or more of the other elements in the mixed oxide can be present in an oxidation state lower than its highest oxidation state, and wherein a, b, c, d, e and f represent the molar ratio of the corresponding element to one mole of Mo.
