摘要： An iron. antimony-containing metal oxide catalyst composition comprising as essential components iron, antimony, and at least one element selected from the group consisting of vanadium, molybdenum, and tungsten and a process for producing the same are disclosed, the composition being represented by empirical formula:
wherein Q represents at least one element selected from the group consisting of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Sm, Th, U, Ti, Zr, Hf, Nb, Ta, Cr, Mn, Re, Co, Ni, Ru, Rh, Pd, Os, lr, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, Ga, In, TI, Ge, Sn, and Pb; R represents at least one element selected from the group consisting of B, As, Bi, and Se; and a, b, c, d, e, f, g, h, and i each represent an atomic ratio of the respective element, wherein

a is from 5 to 15,
b is from 5 to 100,
the sum of c, d, and e is from 3 to 15, provided that (i) when the sum of c and e is 0, d/a is more than 1, (ii) when the sum of c and e is not 0, (c + e)/a is more than 0.3,
f is from 0 to 15,
the sum of g and h is from 0 to 10, provided that when h is not 0, (c + d + e)/h is more than 1, and
i is a number of oxygen atom as determined corresponding to the oxides formed by combining the above components,

and said catalyst composition containing a crystalline iron antimonate. The process comprises preparing a slurry essentially containing (i) crystalline iron antimonate and (ii) at least one element selected from the group consisting of vanadium, molybdenum, and tungsten and optionally containing (iii) at least one element selected from the group consisting of the catalyst components represented by Q, R and P, drying the aqueous slurry, and calcining a dried material. The catalyst exhibits excellent activity and physical properties. The process has improved reproducibility.
