A process for preparing acrylonitrile from propylene, which comprises contacting a mixture of propylene, molecular oxygen and ammonia in the vapor phase at a temperature of about 380 DEG to about 500 DEG C. and a pressure of about atmospheric pressure to about 3 Kg/cm2-G with a catalyst composition comprising active components of the following empirical formula FeaSbbMecTedQeRfOg WHEREIN Me is at least one element selected from the group consisting of V, Mo and W; Q is at least one element selected from the group consisting of Cu, Mg, Zn, La, Ce, Al, Cr, Mn, Co, Ni, Bi and Sn; and R is at least one element selected from the group consisting of P and B; a, b, c, d, e, f and g each represents atomic ratios, and when a is 10, 15</= b </=60, 1<c </=10, 0.5</= d </=10, 0.1</= e </=10, 0</= f </=5, and g represents the number of oxygen atoms corresponding to the oxides resulting from the combination of the above active components, WHEREIN THE Me and Te components are substantially dissolved in an iron-antimony oxide compound (FeSbO4) to form a solid solution when the composition is or has been, calcined finally at a temperature of about 500 DEG C. to about 900 DEG C. |
