Binodal curves and conjugate the lines were determined for the toluene -n-heptane-sulpholane ternary system at 30℃ and 50℃
and for the sul-oholane-n-heptane-water ternary system at 50℃. From these curves andany of the physical properties of the saturated solutions
such as refractive index or density
the equilibrium liquid-liquid compositions of the two ternary systems were found. The UNIQUAC equation was used to correlate the liquid-liquid equilibrium data of the first ternary system
including the UNIQUAC parameters at 30℃ and 50℃
and the UNIFAC method was used to predict the liquid-liquid equilibrium data of both ternary systems. Agreement between calculated and experimental data is satisfactory.
