Kinetics of oxidative ammonolysis of 4-bromo-o-xylene: III. Conversion of 4-bromo-o-tolunitrile as a substrate

Kinetics of oxidative ammonolysis of 4-bromo-o-tolunitrile on V-Sb-Bi-Zr/γ-Al2O3-oxide catalyst in the temperature range 633-673 K were studied. We found that the rate of conversion of 4-bromo-o-tolunitrile to the target 4-bromphthalonitrile and CO2 was described by the half-order equation with respect to the substrate concentration and was independent of the partial pressures of oxygen and ammonia. The byproducts are 4-bromophthalimide formed through the hydrolysis of 4-bromophthalonitrile, CO2 produced by oxidation of 4-bromo-o-tolunitrile and decarboxylation of 4-bromophthalimide, and 4-brombenzonitrile produced from 4-bromo-o-tolunitrile and 4-bromophthalimide.

Kinetics of oxidative ammonolysis of 4-bromo-o-xylene: II. Formation of by-products

Kinetic laws of formation and expenditure of by-products in the oxidative ammonolysis of 4-bromo-o-xylene in the temperature range 633-693 K were studied. It was shown that 4-bromophthalimide formation at high concentration of ammonia occurs through hydrolysis of 4-bromophthalonitrile; carbon dioxide forms by oxidation of 4-bromo-o-xylene and decarboxylation of 4-bromophthalimide; 4-bromobenzonitrile originates from 4-bromo-o-tolunitrile and 4-bromophthalimide. At low concentration of ammonia additional formation routes of 4-bromophthalimide and CO2 from 4-bromo-o-xylene are realized.
