摘要：

Solid-liquid equilibria for three binary mixtures, n-Eicosane (1) +Lauric acid (2), n-Tetracosane (1) +Stearic acid (2), and n-Octacosane (1) +Palmitic acid (2), were measured using a differential scanning calorimeter. Simple eutectic behaviour was observed for these systems. The experimental results were correlated by means of the modified UNIFAC (Larsen and Gmehling versions), UNIQUAC and ideal models. The root-mean-square deviations of the solubility temperatures for all measured data vary from 0.26 to 3.15 K and depend on the particular model used. The best solubility correlation was obtained with the UNIQUAC model.
