Claims
- 1. A process for producing acrylonitrile or methacrylonitrile, which comprises subjecting propane or isobutane and ammonia to gas-phase contact catalytic oxidation reaction in the presence of a complex oxide solid catalyst consisting of molybdenum, vanadium, tellurium, niobium and oxygen, represented by the following formula:
- Mo.sub.1.0 V.sub.a te.sub.b Nb.sub.o O.sub.x
- wherein a, b and c represent the atomic ratio of each of the elements to one atom of Mo, a being 0.01 to 1.0, b ;being 0.1 to 0.5 and c being 0.01 to 1.0, and x represents a number decided by a total number of valences of the metal elements, thereby converting said propane or isobutane to a corresponding mononitrile.
- 2. A process according to claim 1, wherein said gas-phase contact catalytic reaction is carried out in the presence of molecular oxygen.
