Tetraethylammonium chlorochromate oxidised acrylic acid in aqueous acetic acid (50 % v/v) medium in presence of perchloric acid to the epoxide as the oxidation product. The rate of the reaction was dependent on the first power of the concentration of oxidant, substrate and acid. Ionic strength variation has no effect on the reaction rate. The reaction does not induce polymerization. The reaction rate increased with increasing amount of acetic acid in the mixture. Thermodynamic and activation parameters for the reaction have been computed from the data on the temperature dependence. A suitable mechanism consistent with the observed kinetic results has been postulated.

The oxidation of maleic acid by tetraethylammonium chlorochromate (TEACC) was studied, in the presence of perchloric acid and in acetic acid-water mixtures (50 % v/v). The reaction is first order with respect to maleic acid, tetraethylammonium chlorochromate and acid. Ionic strength changes have no significant effect on the reactivity. The reaction does not induce polymerization of acrylonitrile. The reaction rates were determined at different temperatures and the activation parameters were computed. The reaction rate increased with increasing amount of acetic acid in the mixture. A suitable mechanism consistent with the observed kinetic results has been proposed.
