Kinetics of oxidative ammonolysis of 4-bromo-o-xylene: V. Synthesis of 4-bromophthalonitrile

Oxidative ammonolysis of 4-bromo-o-xylene on a V-Sb-Bi-Zr/γ-Al 2O3 catalyst gives 74.82 mol % of 4-bromophthalonitrile at a high conversion of the starting xylene in a one-cycle process. The process with recirculation results in decreased number of by-products and contribution of deep oxidation and increased selectivity in 4-bromophthalonitrile up to 95.42-96.58%.

Kinetics of oxidative ammonolysis of 4-bromo-o-xylene: I. Transformations of 4-bromo-o-xylene and 4-bromo-o-tolunitrile

Kinetic laws of 4-bromo-phthalonitrile synthesis by vapor-phase oxidative ammonolisis of 4- bromo-o-xylene in the range of 633-69 K were studied. It was shown that formation of 4-bromophthalonitrile proceeds successively through 4-bromo-o-tolunitrile. Conversion rates of 4-bromo-o-xylene and 4-bromo-o- toluinitrile were found to be described by half-order equations on the corresponding components and not to depend on the oxygen and ammonia concentrations.
