Abstract : Solvolytic stability of the water disinfectants Chloramine-B (CB) Chloramine- T (CT) and N-Chlorosuccinimide (NCS) in methanol/water and isopropyl alcohol/ water mixtures were studied. The values of the hydrolytic first-order rate constants were explained by a mechanism in which the N-chloramine exists in a rapid reversible equilibrium with a heterolytic dissociation products followed by a slow solvent molecule-assisted and proton-assisted rate determining step. The variation of the values of the observed rate constants with solvent composition has been explained in terms of the sum of the two rate constants, a hydrolysis rate constant and an alcoholysis rate constant. The rate of reaction varies in a non-linear manner and shows extremum behavior with changes in solvent composition, which suggest strong dependence of the reaction rate on solvent structure. The enthalpies and entropies of activation of the solvolytic decomposition reactions were calculated as a function of solvent composition and the results were discussed from the viewpoint of the electrostatic theory and the changing of solvent structure.
