Abstract
A complete kinetic study of the N-chlorination, in aqueous medium, of dimethylamine and diethylamine by a stopflow spectrophotometric method is presented. In neutral or basic medium our experimental results can be interpreted by two kinetically indistinguishable mechanisms; the reactions between protonated amine (R2NH2+) and hypochlorite ion (ClO−) and the reaction between R2NH and hypochlorous acid (ClOH) are equivalent because of the fast equilibrium of proton exchange existing between the two groups of possible reactants [Formula: see text]. In acid medium, in the presence of chloride ions, we observed a reaction by aqueous chlorine (Cl2) on the amine (Cl2 + R2NH → chloramine).Keywords: kinetics, N-chlorination, amines, aqueous medium.
