PURPOSE:To obtain a nitrile readily, in high selectivity and in high yield, by catalytically reacting an alkyl-substituted hetero aromatic compound with NH3 and molecular O2 in a gas phase by using a catalyst having heat resistance and reduction resistance, capable of being stably operated for a long period of time continuously. CONSTITUTION:An alkyl-substituted hetero aromatic compound such as (di)alkyl- substituted pyrazine is catalytically reacted with NH3 and molecular O2 in a gas phase by using an oxide comprising a composition shown by the formula (A is Ce, Mn or W; a, b, c, d and e are each atomic ratio of Mo, P, V, A and O; when a is fixed to 1, b is 0.1-7, c is 0.01-2, d is 0-5 and e is value determined from valence of O and valence and atomic ratio of other elements) such as composition shown by formula II, formula III, formula IV or formula V as a catalyst at 300-650 deg.C at 200-10,000Hr<-1> space velocity under normal pressure to give a hetero aromatic nitrile useful as a raw material for drugs and agricultural chemicals. |
