Liquid–liquid equilibria for mixtures of (ethylene carbonate+aromatic hydrocarbon+cyclohexane)

(Liquid+liquid) equilibria of ternary and quaternary systems containing n-hexane, toluene, m-xylene, propanol, sulfolane, and water at T=303.15K

“…The solutions were made by mass using a Sartorius analytical balance (Model A200S, accurate to 0.0001 g). The mixtures were prepared inside the cell and vigorously agitated with a magnetic stirrer for 3 h, and then left to settle for at least 16 h. The experimental procedures in sample mixture preparation and analyzing of both liquid phases are described in previous works [1][2][3]. The operating condition of the GLC measurements is given in table 1.…”

“…Design of apparatus and determining the optimum operating conditions for aromatic extraction systems require the knowledge of multi-component (liquid + liquid) equilibrium (LLE) data [1][2][3][4]. Such experimental LLE data are usually not available and therefore should be predicted using various thermodynamic models such as activity coefficient.…”

(Liquid+liquid) equilibria for ternary mixtures of (ethylene glycol+toluene+n-octane)

“…In this line of research, the theoretical and experimental studies of (liquid + liquid) equilibrium (LLE) for different systems were presented in the literature [9][10][11]. The basic aim of these investigations was focused on the finding a non-toxic, inexpensive, and easily recoverable solvent for (liquid + liquid) extraction processes in the industrial units [12].…”

(Liquid+liquid) equilibria in ternary aqueous mixtures of phosphoric acid with organic solvents at T=298.2K

“…We have recently reported [21] LLE results for the aqueous mixtures of phosphoric acid with 1-butanol and butyl acetate at T = 308.2 K, where a Type 1 (liquid + liquid) phase diagram was obtained for both the ternary systems. As a continuation of that previous work, we present the LLE results for the three ternary systems (water + phosphoric acid + cyclohexane), (water + phosphoric acid + isobutyl acetate), (water + phosphoric acid + 2-methyl-2-butanol) at T = 298.2 K. These organic solvents widely used as extractants to determination of LLE data for many ternary mixtures [22][23][24][25][26][27][28][29].…”
