ABSTRACT
The liquid-liquid equilibrium of the water + propargyl alcohol + n-propyl acetate ternary system was experimentally investigated in the temperature range (279.15 to 321.15) K under atmospheric pressure. Five profiles of isothermal liquid-liquid equilibrium data measured through gas chromatography were provided. The extraction efficiency was evaluated using the distribution coefficient and selectivity factor. Binary interaction parameters were obtained by correlating the equilibrium data with the UNIQUAC and NRTL models. The mutual solubility of both phases increased with rising temperature. Both models can accurately describe the liquid-liquid equilibrium behavior of this system.
