β¦ Synopsis
The kinetics of the disproportionation of N -C1-n-propylamine and N-C1-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 -C1-3-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 a for these three N-chloramines.

The formation of N-chlorobutylamines is a reaction of order one with respect to hypochlorite and amine, and order -1 with respect to OH-. Kinetic studies show that N-chlorobutylamines undergo decomposition in basic aqueous media, and disproportionation (with formation of N,N-dichloramines) in acidic
