PROBLEM TO BE SOLVED: To provide a catalyst for producing acrylonitrile, acrylic acid, and the like useful as industrial raw materials from alkanes. SOLUTION: This catalyst is a compounded oxide having a general formula; Nba Bib Vc Ze On; for (amm)oxidization of alkanes. In the formula, X stands for one or more elements selected from titanium, iron, and aluminum; Z for tungsten; and a, b, c, d, e, and n can be defined as b=0.1-9; c=0.1-10; d=0-5; e= 05; and n is the number determined by the oxidation valence of other elements in the case a=10. |
