✦ Synopsis

The kinetics and the equilibrium constant of the chlorine transfer reaction between monochloramine NH2C1 and the amines: C2H5NH2, (CH&CHNH,, (CH3)nNH, and (C2H&NH are investigated by spectrophotometry in aqueous medium at 25"C, in the pH range from 8 to 13 and for a n ionic strength equal to 1.03 t 0.05M. For a concentration of total ammonia equal to l M , the observed rate constant is pH independent below 8 and above 12.8 and reaches a maximum located between the pK,s of NH4+ and RR'NHzt. From these results and those obtained earlier for NH&l and C H ~N H Z , the reaction is shown to involve a n interaction between neutral molecules NHZCl and RR'NH, subject to general acid catalysis. The ability of a n interaction corresponding to a specific catalysis and involving NHaCl' and RR'NH rather than NH2C1 and RR'NH2' is also discussed. The activation parameters are given for each reaction.
