Liquid-liquid equilibria for the system water + propionic acid + 1-butanol at 303.2 K. Effect of addition of sodium chloride

Influence of electrolytes on liquid-liquid equilibria of water/1-butanol and on the partitioning of 5-hydroxymethylfurfural in water/1-butanol

“…Electrolytes are known to have a strong influence on the mutual solubility of water and organic solvents as well as on the partitioning of a product between water and the organic solvent. Thus, the systematic study of the salt effects on liquid-liquid equilibria (LLE) of involved liquid mixtures is a prerequisite for the design of extraction separation processes [10,11]. as organic solvent is especially interesting from environmental aspects.…”

Liquid - liquid equilibria of the water + butyric acid + decanol ternary system

“…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 equilibria of the water-acetic acid-butyl acetate system

“…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).…”
