  • Abstract

    Oxidation of S-phenylmercaptoacetic acid by piperidiniumchlorochromate (PipCC) in the presence of perchloric acid has been studied in 50% (v/v) aqueous acetic acid medium. The reaction shows unit order dependence each with respect to oxidant and substrate. The order with respect to hydrogen ion concentration is fractional. The rate of oxidation increases with increase in the percentage of acetic acid and increase the ionic strength has negligible effect on the reaction rate. Number of electron transferred during the oxidation process has also determined. From the kinetic observations, the reaction mechanism and rate law has been proposed.
