INTERACTIONS OF METAL EXTRACTANT REAGENTS .7. AGGREGATION OF TRI-N-DODECYLAMMONIUM CHLORIDE AND PERCHLORATE IN TOLUENE AT 40-DEGREES-C

The self-association and mixed species formation equilibria of tri-n-dodecylammonium chloride (TLAHCl) and tri-n-dodecylammonium perchlorate (TLAHClO4) dissolved in toluene have been studied by vapor pressure osmometry at 40-degrees-C. The experiment data can be fitted best by the formation of the aggregates (TLAHCl)2 (log beta2,0 = 1.35 +/- 0.06), (TLAHClO4)2 (log2 beta0,2 = 2.4 +/- 0.1) and the mixed species (TLAHCL) (TLAClO4)2 (log beta1,2 = 6.4 +/- 0.5), (TLAHCl)2(TLAHClO4) (log beta2,1 = 7.1 +/- 0.6) and (TLAHCl)2(TLAHClO4)2 (log beta2,2 = 9.9 +/- 0.7).
