Kinetics of oxidation of allyl alcohol by imidazoliumdichromate

The kinetics of oxidation of allyl alcohol by imidazolium dichromate has been studied in 40% acetic acid- water (v/v) medium in the presence of perchloric acid at 313 K. The reaction is first order with respect to [oxidant] and [substrate] . The reaction is acid catalysed one. The decrease in dielectric constant of the medium increases the rate of the reaction. Increase in Ionic strength by the addition of sodium perchlorate has no effect on the rate constant. There is no polymerization with acrylonitrile. The reaction has been studied at four different temperatures and the activation parameters were calculated. Acrolein has been identified as the product of oxidation. From the observed kinetic results a suitable mechanism consistent with rate data has been proposed
