PROBLEM TO BE SOLVED: To obtain the subject compound in a high yield by using a five component-based catalyst of a specific composition and catalytically reacting an alkyl-substituted aromatic compound or an alkyl-substituted heterocyclic compound with a mixed gas containing ammonia and oxygen. SOLUTION: In catalytically reacting an alkyl-substituted aromatic compound or an alkyl-substituted heterocyclic compound with a mixed gas containing ammonia and oxygen on a catalyst, a catalyst comprising a vanadium oxide, a chromium oxide, a boron oxide, a molybdenum oxide and an alkaline (earth) metal is used. Lithium, sodium, magnesium, calcium or the like is preferable as the alkaline (earth) metal. The atomic ratio of vanadium, chromium, boron, molybdenum and the alkaline (earth) metal is preferably 1:(0.5-2):(0.01-1.5):(0.01-1.5):(0.005-0.2). Preferably the catalyst is obtained by supporting the catalytic components on silica. |
