The kinetics of Os(VIII) catalysed oxidation of 2-m ethyl cyclohexanol by alkaline chloramine-T has been investigated. The result indicates zero or der 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 io nic strength, para-toluene sulphonamide (PTS) and KCl on reaction rate. The dielectric constant o f the medium shows positive effect. Elevation of temperature increases the rate of reaction in ox idation of 2-methyl cyclohexanol. A suitable mechanism in conformity with the above observation has been proposed
