The kinetics of Os(VIII) catalysed oxidation of 2-methyl cyclohexanol by alkaline chloramine-T has been investigated. The result indicates zero order kinetics with respect to 2-methyl cyclohexanol and first order kinetics with respect to chloramine-T, OH – and Os(VIII) concentrations. There is insignificant effect of ionic strength, para-toluene sulphonamide (PTS) and KCl on reaction rate. The dielectric constant of the medium shows positive effect. Elevation of temperature increases the rate of reaction in oxidation of 2-methyl cyclohexanol. A suitable mechanism in conformity with the above observation has been proposed.
