Phase diagrams of (R4N)2[Nd(NO3)5]-carbon tetrachloride-n-octanol (n-butanol, n-decanol, cyclohexanol) liquid ternary systems at various temperatures

Phase diagrams are studied for (R₄N)₂Nd(NO₃)₅]-CCl₄ n-octanol (n-butanol, n-decanol, cyclohexanol) ternary liquid systems, where R₄N⁺ stands for trialkylbenzylammonium, at T = 298.15–333.15 K. The (R₄N)₂Nd(NO₃)₅]-CCl₄ binary system at all temperatures is a two-phase liquid. One phase (phase I) is almost neat carbon tetrachloride; the other (phase II) is enriched in (R₄N)₂Nd(NO₃)₅]. The CCl₄ solubility in phase II increases with rising temperature. The liquid ternary systems are characterized by homogeneous and two-phase liquid solution fields. One phase is enriched in (R₄N)₂Nd(NO₃)₅] and n-octanol (n-butanol, n-decanol, cyclohexanol) and the other in CCl₄. Miscibility fields in the ternary liquid systems narrow with rising temperature.
