Liquid-liquid equilibria of the water + acetic acid + cyclohexyl acetate ternary

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).…”

(Liquid + liquid) equilibria of some (water + tetrahydrofuran + solvent) ternaries at the temperature (293.2 ± 0.1) K and pressure (101.3 ± 0.7) kPa

“…(1,4,6) In order to obtain central and solvent-side parts of the curve, (water + solvent) of known composition was titrated with tetrahydrofuran until the mixture became homogeneous. The water-side segment of the curve was obtained by titrating (water + tetrahydrofuran) with the solvent until the mixture was turbid.…”

“…As an adjacent part of the previous study, (1) the present work aims to report elementary (l + l) equilibria for five (water + tetrahydrofuran + solvent B) ternaries at the temperature (293.2 2 0.1) K and pressure (101.3 2 0.7) kPa and to discuss the extracting powers of the investigated solvents. Taking into account the technoeconomic merits (2)(3)(4) of high-boiling solvents during the regeneration by distillation, the selection of separating agents was made on the basis that they represent the various classes (5) of extracting compounds. They all have higher boiling temperatures than water, except 1,2-dichloroethane.…”

(Liquid+liquid) equilibria of the (water+acetic acid+dibutyl phthalate) system

“…In the fermentation industry, various solvents have been tried and tested to improve such recovery [1][2][3][4][5][6][7][8][9].…”
