  ABSTRACT: Literature data dedicated to formation of 4-phenylphthalonitrile were analyzed and generalized. As a result of the own studies, it has been established that on V–Sb–Bi–Zr/γ-Al2O3-oxide catalyst ammoxidation gives 83.10 mol.% 4-phenylphthalonitrile at high conversion of the initial 4-phenyl-o-xylene in a single process. In connection with increased demand to purity of 4-phe-nylphthalonitrile at using and division problem of hard-separable impurity of crystal 4-phe-nylphthalimide, a variant of the technological process design with average conversion and recirculation of the unreacted 4-phenyl-o-xylene and intermediate 4-phenyl-o-tolunitrile was proposed. In contrast to the single process, it has been determined that recirculation reduces quantity of form by-products, fractions of deep oxidation and increases selectivity on 4-phenylphthalonitrile up to 96.14% - 97.72%. For the data analysis and visualization of results it is developed and offered the software package of OptimMe written in C#.
