Ohtaki, Hitoshi published the artcileIonic equilibriums in mixed solvents. VI. Dissociation constants of aliphatic diamines in water-methanol solutions, HPLC of Formula: 10517-44-9, the publication is Journal of Physical Chemistry (1971), 75(1), 90-2, database is CAplus.
Dissociation constant of protonated 1,2-diaminoethane, 1,3-diaminopropane, and 1,4-diaminobutane have been determined potentiometrically at 25¡ã in various H2O-MeOH mixtures containing 0.1M NaCl as an ionic medium. Ion products, Kw(S), in the mixtures have been calculated and used for calculations of pK’s of the acids, equilibrium of hydronium ions with alkoxonium ions being taken into consideration. Since values of pK2 – pK1 of the diamines have been independent of solvent compositions, interactions between charged sites in a mol. may scarcely be affected with the variation of the solvent composition
