摘要：Kinetic investigation on the oxidation of isatin in an acidified solution of peroxomonosulphate has been studied inthe temperature range of 323-333K. Increase in the concentration of H+ ion showed first order. The influence ofionic strength and oxidant on the rate was found to be insignificant. The various thermodynamic parameters werecalculated form rate measurements at 323, 328 and 333K respectively. A suitable mechanism in conformity with thekinetic observations has been proposed and the rate law was derived on the basis of the observed data. The productisatoic anhydride was confirmed from the IR&NMR spectral analysis.
