The kinetics of epoxidation of crotonic acid with hydrogen peroxide catalysed by sodium orthovanadate have been investigated at 40⁰C. The rate of epoxidation reaction is first order with respect to the [substrate] and [catalyst] and zero order in hydrogen peroxide concentration. The strength of the medium shows insignificant effect on the reaction rate. Temperature dependence parameters have been computed. On the basis of kinetics and experimental results, a suitable mechanism is proposed.
