Kinetic investigations in Keggin-type phosphotungstic acid catalyzed oxidation of benzyl alcohol by Nchlorosaccharin, (NCSA) in aqueous acetic acid have been studied. Oxidation kinetics of benzyl alcohol by N-chlorosaccharin in presence of Phosphotungstic acid (PTA) shows a first order dependence on NCSA and fractional order on benzyl alcohol and PTA. The variation of [H+] and [saccharin] (reaction product) have insignificant effect on reaction rate. Activation parameters for the reaction have been evaluated from Arrhenius plot by studying the reaction at different temperature. The rate law has been derived on the basis of obtained dat and a plausible mechanism has been proposed.
