Kinetics and Mechanism of Rapid Oxidation of Acetaminophen by Sodium Periodate in the Presence of Catalyst

Kinetic studies of the novel oxidation of acetaminophen by sodium periodate are discussed with an emphasis on structure and reactivity by using kinetic approach. The reactions were catalyzed by Os(VIII). The kinetics of the reaction was studied as a function of temperature, ionic strength, dielectric constant of the medium, concentrations of the salt and the added reaction product to learn the mechanism of the reaction. The active species of catalyst and oxidant have been identified. Activation parameters have also been evaluated using the Arrhenius and Eyring plots. A suitable mechanism consistent with the observed kinetic results has been suggested and the related rate law deduced.
