| Abstract: | The kinetics of the disproportionation of N ? Cl-n-propylamine and N – Cl-isopropylamine to the corresponding N, N-dichloramines were found to be a second order with respect to the N-chloramine. The influence of amine concentration, pH, buffers, ionic strength, and temperature were also studied. The observed influence of pH supports a reaction mechanism which allowed estimation of the protonation constants of the chloramines studied. The influence of buffers, which was studied for both the above chloramines and N ? Cl-3-aminopropanol, reflects general acid catalysis, for which a mechanism is proposed. Bronsted's equation was fitted to the catalytic constants obtained therefrom so as to estimate the values of the parameter α for these three N-chloramines. © John Wiley & Sons, Inc. |
