Thermodynamics of Protonation of Aqueous Triethylenediamine
Journal of Chemical and Engineering Data
Abstract
Calorimetric determinations of heats of solution of solid triethylenediamine in water and in aqueous acid at 25°C. lead to the following: NR3NH+(aq) = H+(aq) + NR3N(aq) ΔH° = 7.21 kcal. per mole and +HNR3NH+(aq) = 2H+(aq) + NRN(aq) ΔH° = 10.18 kcal. per mole. Combination of these ΔH° values with ΔG° values from ionization constants leads to ΔS° = -15.2 and ΔS° = -18.8 cal. deg. -1 mole-1 for the two ionization reactions indicated above.
