Abstract
Ternary liquid-liquid equilibrium data for the systems benzene-sodium-ammonia and cyclohexene-sodium-ammonia were measured at 20°C. A method for prediction of the mutual solubility of sparingly soluble mixtures in the ternary liquid-liquid equilibria was proposed by the application of Ishida''s correlation using the data of the ternary liquidliquid equilibria. On the basis of the above results, a point at which solid and heterogeneous liquids are in equilibrium was determined.
