Abstract
Protonation constants of triethylenetetramine (trien) and tetraethylen epentamine (tetren) were determined, in NaCl aqueous solutions, at dif ferent ionic strengths, at 25-degrees-C, using the the pH-metric techn ique. The behavior of protonation constants as a function of ionic str ength can be explained by a model which takes into account the formati on of the species AH(q)Cl(p) [A = amine; q = 1 ... 4, p = 1,2 (trien); q = 1 ... 5, p = 1 ... 3 (tetren)].
