A Kinetics study of miceller catalysed oxidation of propionic acid by acidic permanganate

A kinetic study of oxidation of propionic acid has been investigated in presence and absence of anionic micelle; sodium lauryl sulphate (NaLS). The reaction is a double stage process, in which first stage is followed by second fast stage process. It is observed that the rate was increased in the presence of surfactant used. A first order kinetics is observed with respect to substrate and oxidant. The data has been examined in the light of Zucker-Hammett, Bunnett and Bunnett-Olsen criteria of reaction mechanism.The stiochiometry was observed in terms of mole ratio of permanganate ion and propionic acid consumed. Effect of specific ions on the reaction rate has also been reported. Activation parameters for the reaction are evaluated and the plausible mechanism is suggested.
