Interactions of metal extractant reagents .9. Aggregation and mixed species equilibria of tri-n-dodecylammonium chloride and nitrate in toluene at 40 degrees C

The aggregation and mixed species formation equilibria of tri-n-dodecylammonium chloride (TLAHCl) and tri-n-dodecylammonium nitrate (TLAHNO(3)) dissolved in toluene have been studied by vapor pressure osmometry at 40 degrees C. The experimental data can be best fit by the formation of the aggregates (TLAHCl)(2) (log beta(2,0) = 1.35+/-0.06), (TLAHNO(3))(2) (log beta(0.2) = 1.75+/-0.20), (TLAHNO(3))(3) (log beta(0.3) = 3.6+/-0.1), and the mixed species (TLAHCl)(TLAHNO(3))(2) (log beta(1,2) = 3.3+/-0.2).
