摘要：
Protonation constants of triethylenetetramine (trien) and tetraethylenepentamine (tetren) were determined, in NaCl aqueous solutions, at different ionic strengths, at 25-degrees-C, using the the pH-metric technique. The behavior of protonation constants as a function of ionic strength can be explained by a model which takes into account the formation of the species AH(q)Cl(p) [A = amine; q = 1 ... 4, p = 1,2 (trien); q = 1 ... 5, p = 1 ... 3 (tetren)].
