KINETICS AND MECHANISM OF CATALYTIC HYDROXYLATION OF PHENOLS WITH HYDROGEN-PEROXIDE - VI - THE PHYSICAL MODEL AND REACTION-MECHANISM

The mechanism of catalytic hydroxylation of phenols, based on the prin ciples of the metallocomplex catalysis and considering the effect of v arying initial parameters, including pH of the medium, is proposed in analyzing the regularities of the peroxide oxidation of mono- and diox ybenzenes and the overall mathematical model of the catalytic hydroxyl ation of phenols. The physical meaning of all terms in the kinetic equ ations of the model is considered, and the corresponding constants are determined. The possible structure of the intermediate hydroxylation complex and the effect of cerium sulfate additives on the reaction sel ectivity are discussed using the spectral data.
