Kinetic measurements and oxidation mechanism of phenol by pyrazinium chlorochromate (PzCC) catalysed by perchloric acid has been studied. The main yield of the product of oxidation was benzoquinone. The reaction obeyed first order with respect to [PzCC] and fractional order with respect to [phenol] and [H+]. The rate constant of the reaction decreased with the increase in [O].The temperature effect was studied at 293K, 303K, 313K and 323K and thermodynamic parameters (ΔH#, ΔG#, Ea and -ΔS#) were evaluated using Eyrings plot. Based on these evidences a plausible mechanism of oxidation of phenol is proposed. Keywords—Oxidation, phenol, pyrazinium chlorochromate, kinetics, mechanism.
