Abstract

The kinetics of oxidation of benzyl alcohol and substituted benzyl alcohols by sodium N‐chloro‐p‐toluenesulfonamide (chloramine‐T, CAT) in HClO~4~ (0.1–1 mol/dm^3^) containing Cl^−^ ions, over the temperature range of 30–50°C have been studied. The reaction is of first order each with respect to alcohol and oxidant. The fractional order dependence of the rate on the concentrations of H^+^ and Cl^−^ suggests a complex formation between RNCl^−^ and HCl. In higher acidic chloride solution the rate of reaction is proportional to the concentrations of both H^+^ and Cl^7hyphen;^. The observed solvent isotope effect (k/k) is 1.43 at 30°C. The reaction constant (p = −1.66) and thermodynamic parameters are evaluated. Rate expressions and probable mechanisms for the observed kinetics have been suggested.
