Claims
- 1. In an ammoxidation process in which oxygen, ammonia and a reactant selected from the group consisting of propylene and isobutylene in the vapor phase are contacted with a catalyst at elevated temperatures and a pressure of 14 or less atmospheres, the improvement wherein said catalyst comprises a manganese antimonate oxide complex of the formula:
- A.sub.a D.sub.b C.sub.c Mn.sub.d Sb.sub.12 O.sub.x
- wherein
- A is at least one of Cu, Ag, V, W and/or Mo;
- D is Te and/or Cr;
- C is optional elements selected from Ce, La, Mg, Ca, Co, Ni, Nb, Ta, Zn, Cd, K, Cs, B, P and/or Eu; and
- wherein
- a is 0.5 to 5;
- b is 0.1 to 2;
- c is 0 to 10;
- d is 2.4 to 10; and
- x is determined by the valence requirements of the other elements present, and
- wherein A is selected so that said oxide complex at least contains Cu and at least one of Mo and W, and further wherein said oxide complex is substantially free of Fe, U, and Sn.
- 2. The process of claim 1 wherein C is at least one element selected from Ce, La, Mg, Co, Ni, Nb, Zn, K and/or Cs and further wherein c is at least 0.001.
- 3. The process of claim 1 wherein said catalyst contains W.
- 4. The process of claim 1 wherein said catalyst contains Mo.
