Abstract
The kinetics and mechanism of the oxidation of maleic and fumaric acids by hydrogen peroxide in the presence of ferrous sulphate has been studied. The oxidation rate of fumaric acid is faster than that of maleic acid. The reaction is first order with respect to maleic acid or fumaric acid and first order with respect to ferrous sulphate but zero order with respect to hydrogen peroxide. The energies of activation have been calculated to be 24.36 and 38.29 kj mol-1 for maleic and fumaric acids, respectively. A reaction mechanism has also been proposed.
