A process for preparing acrylonitrile comprises ammoxidising propylene in the presence of a complex oxide catalyst having the empirical formula: AaBbCcDdFeeBifMo12Ox where A is Cs, K or mixtures thereof B is one or more of Mg, Mn, Ni, Co, Ag, Pb, Re, Cd and Zn or mixtures thereof C is one or more of Ce, Cr, P, Ge and mixtures thereof D is Ca and optionally one of Sr, Ba or mixtures thereof and a = 0.01 to 1.0 b and e = 1.0 to 10 c, d and f = 0.1 to 5.0 and x is a number determined by the valence requirements of the other elements present. |
