SummaryThe ternary systems, oleic acid‐palmitic acid‐commercial hexane and oleic acid‐palmitic acid‐acetone, containing varying amounts of the three components have been equilibrated at 0°C., −10°C., −20°C., −30°C., and −40°C. From compositional data of the liquid and solid phases in equilibrium at each isothern, ternary phase diagrams have been constructed. From these diagrams it is possible to predict the degree of separation which can be obtained with any given mixture of oleic and palmitic acids, using either acetone or commercial hexane as solvent. The liquid phase boundaries have been established for each isotherm investigated and have been constructed on an enlarged scale. The intersolubilizing effect of oleic acid on palmitic acid is greater in commercial hexane than in acetone although each acid is more soluble in acetone than in commercial hexane.
