  ABSTRACT: On the basis of kinetic data of 4-phenyl-o-xylene and 4-phenyl-o-tolunitrile ammoxidation, formation mechanism of the products was analyzed and generalized. It has been shown that dissociative adsorption of a substrate and mononitrile occurs on the centers with high heats of adsorption of oxygen and as a consequence, completely covered with it, competitive adsorption of NH3 and O2 occurs on the centers with low heats of adsorption of the latter; mononitrile and dinitrile are formed correspondingly from adsorbed fragments of both substrate and NH3, and tolunitrile and NH3; surface interaction of adsorbed fragments of substrate and O2 with low heat of adsorption gives imide and CO2; hydrolysis of dinitrile into imide occurs on centers completely covered with ammonia; imide decarboxylation occurs on the centers covered with it; oxidative destruction of tolunitrile occurs on centers covered with substrate and mononitrile.
