%X The major component of turpentine is ¦Á-pinene and the main hydration product of ¦Á-pinene is ¦Á-terpineol. To obtain the optimal process design of ¦Á-terpineol production, some initial information regarding the principle of the thermodynamics and phase equilibrium are required. The aim of this paper is to present liquid-liquid equilibrium (LLE) of system containing ¦Á-pinene, ¦Á-terpineol and water. Ternary LLE for ¦Á-pinene, ¦Á-terpineol and water system was determined by experiment at the temperatures of 301, 327 and 353 K and atmospheric pressure. The three component mixture was stirred for about 30 min, then the mixture was left for about 2 h for complete phase separation. The composition of both phases was analyzed by using a Gas Chromatograph. The thermodynamic equilibrium models were proposed. LLE model in this study includes activity coefficient model based on NRTL and UNIQUAC models. The NRTL model (¦Á = 0.2) correlates the LLE data for the system of ¦Á-pinene + ¦Á-terpineol + water at the temperatures 301, 327 and 353 K with RMSD of 0.5464%, 0.000169% and 0.0054%, respectively. The UNIQUAC model correlates the LLE data for the system of ¦Á-pinene + ¦Á-terpineol + water at the temperatures 301, 327 and 353 K with RMSD of 0.756%, 1.314% and 1.6615%, respectively. The LLE data for the system of ¦Á-pinene + ¦Á-terpineol + water were successfully correlated using the NRTL and UNIQUAC models at that temperatures
