Abstract

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.
