“…As the separation by solvent extraction depends on mutual solubility of the (water + propionic acid) mixture, the variation of solubility of organic solvent in the mixture is an important feature in the LLE investigations. Significant investigation has been carried out in recent years on the LLE measurements and the extraction of propionic acid from aqueous solutions [8][9][10]. Many organic solvents such as dipropyl ether, octanol, cyclohexanone, dimethyl phthalate, and isopropyl methyl ketone, have been used to improve such recovery [11][12][13][14].…”

Liquid + liquid) equilibrium (LLE) data of the solubility (binodal) curves and tie-line end compositions were examined for {water (1) + propionic acid (2) + diethyl succinate or diethyl glutarate or diethyl adipate (3)} at T = 298.15 K and 101.3 ± 0.7 kPa. The relative mutual solubility of the propionic acid is higher in the dibasic esters layers than in the aqueous layers. The reliability of the experimental tie-line data was confirmed by using the Othmer-Tobias correlation. The LLE data of the ternary systems was predicted by UNIFAC method. Distribution coefficients and separation factors were evaluated for the immiscibility region.

Abstract-The major component of turpentine is α-pinene and the main hydration product of α-pinene is α-terpineol. To obtain the optimal process design of α-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 α-pinene, α-terpineol and water. Ternary LLE for α-pinene, α-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 (α = 0.2) correlates the LLE data for the system of α-pinene + α-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 α-pinene + α-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 α-pinene + α-terpineol + water were successfully correlated using the NRTL and UNIQUAC models at that temperatures.
