Abstract
The present invention relates to a novel multicomponent oxide catalyst, more specifically, a highly active and selective catalyst composition which plays a vital role to produce unsaturated nitrile compounds by reacting paraffinoid hydrocarbons with ammonia and oxygen. The formula of catalyst composition of the present invention is represented as A.sub.a B.sub.b C.sub.c D.sub.d In.sub.e Ga.sub.f Bi.sub.g Mo.sub.i O.sub.x. wherein: PA0 A is alkali metal, alkali earth metal, silver or copper; PA0 B is nickel, cobalt, iron, chromium, ruthenium, palladium or manganese; PA0 C is zinc, cadmium, cerium, tin, phosphorus, antimony, lead, tellurium, germanium or aluminum; PA0 D is titanium, zirconium, vanadium, niobium, tantalum, lanthanum, neodymium, gadolinium or tungsten; and, a, b, c, d, e, f, g and i is the mole of each component, wherein, a is 0 to 10; b is 0 to 5; c is 0 to 15; d is 0 to 14; e is 0 to 2; f is 0 to 7; g is 1 to 25; i is 12 to 40; and, 12.ltoreq.a+b+c+d+e+f+g.ltoreq.40.
