Surfactant catalyzed oxidation of n-butyric acid has been carried out for kinetic and mechanistic investigations in sulphuric acid medium by molecular HMnO₄ species. Reaction has also been observed in absence of surfactant.The substrate oxidised in two steps in which first step is slow in comparision to second step which fast one. Micelles of surfactant work as positive catalyst. Substrate and oxidant both follows first order kinetics.Different hypotheses have been applied related to the acidity function to arrive the correct reaction mechanism. Number of moles between substrate and oxidant has also been determined. Temperature variation parameters presented in terms of activation parameters, those are found in prescribed limit. Mechanism for reaction has been suggest on the basis of parameters observed.
