摘要：
The catalytic reaction of crystal violet leucobase oxidation by dioxygen in o-dichlorobenzene into corresponding dye was studied as a model of hydrocarbons C-H group oxidation. Substituted iron phthalocyanines in acidic form HPcFeX were used as the catalysts. It was shown that the oxidation process was accompanied in all cases by autocatalytic destruction of catalyst with induction period depending on concentrations of reactants. The kinetics of dye formation and catalyst degradation, as well as the effect of radical reaction inhibitors were studied. The nature of the process main stages was proposed.
