Abstract
Based on the observed kinetics of oxidative ammonolysis of 4-bromo-o-xylene and 4-bromo-o-tolunitrile on oxide catalyst V-Sb-Bi-Zr/g-Al2O3 explained mechanism of formation of main and byproducts. The total conversion rate of the feedstock is not dependent on the partial pressure of NH3, and is described by equation the half-order by 4-bromo-o-xylene, suggesting dissociative adsorption of the substrate on centers which at are completely covered with oxygen. Was shown rather probable superficial stage and discussed the individual characteristics of the formation mechanism of each product.
