Abstract

Phase diagrams on the mole fraction scale are presented for decane- (R4N)2[Nd(NO3)5]-n-octanol(n-butanol, n-decanol) (1–2–3) ternary liquid systems, where R4N+ stands for trialkylbenzylammonium, at T = 298.15 K. The C10H22-(R4N)2[Nd(NO3)5] binary system is a two-phase liquid system. One phase (phase I) is the almost neat solvent; the other (phase II) is enriched in (R4N)2[Nd(NO3)5]. The liquid ternary systems are characterized by homogeneous and two-phase liquid solution fields. One phase is enriched in (R4N)2[Nd(NO3)5] and n-octanol (n-butanol, n-decanol) and the other in C10H22. The miscibilities in the C10H22-(R4N)2[Nd(NO3)5] binary system and in the ternary liquid systems were used to calculate, from the equations of the nonrandom two-liquid model (NTRL), intermolecular interaction parameters and excess Gibbs free energies g E for the binary and ternary liquid systems along the binodal curve. g E > 0 is characteristic of the systems under study, while g E decreases in the series of pairs of liquids (1, 2), (1, 3), and (2, 3)
