“…Production of organic acids such as acetic, citric, lactic, propionic and butyric acids can be given as an example. Extraction can be employed not an only in downstream separation but also in combination with fermentation (Wardell and King, 1978;Hegazi, 1984;Fahim et al, 1992;Arce et al, 1995;Fahim and Al-Muhtaseb, 1996;Fahim et al, 1997;Sólimo et al, 1997;Colombo et al, 1999;Aljimaz et al, 2000;Taghikhani et al, 2001;Trevor et al, 2001;İnce and Kırbaşlar, 2002;İnce, 2005).…”

-Liquid-liquid equilibrium (LLE) data for the water + butyric acid + decanol ternary system were determined experimentally at temperatures of 298.15, 308.15 and 318.15 K. Complete phase diagrams were obtained by determining the solubility curve and the tie lines. The reliability of the experimental tie line data was confirmed with the Othmer-Tobias correlation. The UNIFAC method was used to predict the phase equilibrium of the system using the interaction parameters for groups CH 3 , CH 2 , COOH, OH and H 2 O determined experimentally. Distribution coefficients and separation factors were evaluated for the immiscibility region.

“…Recovery of organic acids from dilute solutions resulting from fermentation processes is important, and many solvents have been tried in attempts to improve recovery (Upchurch and Van Winkle, 1952;Correa et al, 1989;Sayar et al, 1991;Kirk and Othmer, 1992;Dramur and Tatlõ, 1993;Briones et al, 1994;Arce et al, 1995;Fahim et al, 1996;Fahim et al, 1997;Sólimo et al, 1997;Colombo et al, 1999;Aljimaz et al, 2000;Taghikhani et al 2001).…”

-Experimental liquid-liquid equilibria of the water-acetic acid-butyl acetate system were studied at temperatures of 298.15±0.20, 303.15±0.20 and 308.15±0.20 K. Complete phase diagrams were obtained by determining solubility and tie-line data. The reliability of the experimental tie-line data was ascertained by using the Othmer and Tobias correlation. The UNIFAC group contribution method was used to predict the observed ternary liquid-liquid equilibrium (LLE) data. It was found that UNIFAC group interaction parameters used for LLE did not provide a good prediction. Distribution coefficients and separation factors were evaluated for the immiscibility region.
