- Аннотация: The qualitative and quantitative effects of various metal salt additives to iron sulfate on the parameters of the hydroxylation process are investigated. Synergism is observed only on addition of metal salts that do not possess any catalytic activity of their own. The maximum simbatic effect of increasing both the initial rate and the selectivity of the process is revealed in the case of cocatalysis by iron and cerium sulfates. The kinetics of phenol hydroxylation by hydrogen peroxide in the presence of the previously prepared complex of iron and cerium sulfates with catechol is examined in detail. The method of the initial rates is used to obtain the data for developing a model that adequately describes all regularities observed in the range of the initial concentrations of both the reagents 0.25 - 3.0 mol/l and the catalytic system 1 x 10(-5) - 1 x 10(-3) mol/l (with respect to iron sulfate). A comparative analysis of the models of the initial stage of the reaction catalyzed by the FeSO4-catechol system and its analog modified by Ce(SO4)(2) is performed.
