Liquid-liquid equilibria of the system water + acetic acid + methyl isopropyl ketone between 25 and 55.degree.C

Abstract

Thls paper reports experimental data for the solubllity of the binary mixture water + methyl isopropyl ketone at several temperatures In the range 20-55 OC, together with liquid-liquid equlllbrium data for the ternary mlxture water + acetic acid + methyl isopropyl ketone at 25, 35, 45 and 55 OC. NRTL and UNIOUAC equations were fitted satlsfactorlly to the experimental data for the ternary mlxture, but UNI FAC predlctlons agreed only qualitatively with these data.

(Liquid+liquid) equilibria for (water+acetic acid+2-ethyl-1-hexanol): experimental data and prediction

“…Various organic solvents for extraction of dilute acetic acid from water have been investigated and reported in the literature [9][10][11]. Mainly heavy normal alcohols such as 1-hexanol, 1-heptanol, and 1-octanol have been used for extraction of acetic acid from aqueous solution.…”

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 ternary mixtures of dimethyl carbonate, diphenyl carbonate, phenol and water at 358.15K

“…The system designed in our laboratory to measure the liquid-liquid equilibrium is similar to that reported by Correa et al [9]. It consists of three parts: an equilibrium glass vessel jacket, a thermostat (Lauda MD 20 with DLK15 cooler) with a system that precisely measures the temperature (A A F250), and a Corning PC-320 magnetic stirrer.…”
