The solid-liquid equilibrium (SLE) of binary systems containing Alamine 304-1 (tri-dodecylamine), which used as a selective solvent in the extraction of molybdenum (Mo), was measured at atmospheric pressure by the visual method. The experimental SLE data for mixtures of Alamine 304-1 + 1-octanol, Alamine 304-1 + 2-octanol, and Alamine 304-1 + 1-decanol were then correlated to the non-random two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) equations. We correlated the excess molar volume (V-E) and deviations in molar refractivity (Delta R) of the aforementioned binary mixtures at 298.15K using the Redlich-Kister equation. The V-E and Delta R of the ternary mixtures Alamine 304-1 + 1-octanol + 2-octanol, Alamine 304-1 + 1-octanol + 1-decanol, Alamine 304-1 + 2-octanol + 1-decanol, and 1-octanol + 2-octanol + 1-decanol were predicted by the Radojkovic equation using the correlated binary Redlich-Kister parameters.
