dc.description.abstract	Kinetics of oxidation of monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) by sodium Nchloro- p-toluenesulphonamide (chloramine-T, CAT) in alkaline buffer medium has been studied at 313K. The reactions followed identical kinetics being first order in [CAT] and fractional order each in [substrate] and [OH^-]. Under comparable experimental conditions the rate of oxidation increases in the order: DEA > TEA > MEA. Addition of the reaction product p-toluenesulphonamide retards the reaction rate. Added chloride ions and change in ionic strength of the medium do not have any effect on the rate of the reaction . Change in dielectric constant of the medium affects the reaction rate. Activation parameters for the rate determining step are evaluated and isokinetic relation is observed with β=390 K indicating that the reactions are enthalpy-controlled. Formation and decomposition constants of substrate - CAT complexes are evaluated. Suitable mechanisms and rate equations are proposed based on the observed kinetic data.	en_US
