  • Abstract

    The kinetic oxidation study of acetophenone by N-bromosaccharin in aqueous acetic acid medium and in presence of Hg(II) acetate was investigated in the presence of both cationic and anionic micelles. The reaction obeys first order kinetics in oxidant both in the presence as well as absence of micelle. The kinetic results for dependence on substrate concentration indicate intermediate complex formation between oxidant and substrate species. The reactions are acid catalysed and follow both acid dependent and independent path. Change in polarity of the medium, effect of addition of saccharin and Hg(II) acetate have also been investigated. Both type of micelles catalyses the oxidation. Binding parameters have been calculated by analyzing the data using the model suggested by Piszkiewicz. On the basis of kinetic results probable mechanism is proposed
