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 D 2 O / k H 2 O ) 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.
