Abstract:
A process for preparing a heteroaromatic nitrile compound, comprising:ammoxidation of an alkyl substituted heteroaromatic compound in the presence of a solid catalyst of the following formula;Mo.sub.x.P.sub.y.O.sub.zwherein, Mo is molybdenum;P is phosphorus;O is oxygen;x, y and z are respectively a number of atoms, wherein y/x is 0.01.about.5 and z is 0.01.about.10;wherein said solid catalyst further comprises water and ammonium,wherein the solid catalyst is concentrated from a solution comprising a molybdenum salt, comprising water and ammonium and then pretreated in inert gas at about 400.degree. C. to about 600.degree. C. for about 2 to about 6 hours, the water and ammonium remaining in the solid catalyst after said pretreatment.
