in Wiley Online Library (wileyonlinelibrary.com)Vapor-liquid equilibrium (VLE) and liquid-liquid equilibrium (LLE) data of binary and ternary acrylic systems were systematically measured. Subsequently, VLLE phase diagrams of binary systems, tridimensional VLE phase diagrams of methyl acrylate (MA)-methanol (Me)-H 2 O ternary system, and quaternary LLE phase diagrams of MA-Me-H 2 O-methyl acetate (MeOAc) system were constructed. These diagrams clearly demonstrated the effects of temperature on phase equilibrium. The experimental data was fitted by the NRTL and UNIQUAC models, and the best-fitted parameters were used to predict interaction properties of ternary and quaternary mixture. Therefore, the phase equilibrium data were provided as reference for the design of acrylic systems rectification or extraction process. Residue curve was mapped out for MA-Me-H 2 O system through Aspen plus software. Finally, using thermodynamics and residue curve as theoretical basis, two novel separation processes were proposed and applied to the quaternary acrylic systems.

“…Many solvents have been tested, and the phase equilibrium data of the related systems are presented in the literature. Mainly, alcohols, carbonate [9], alkyl carbonates [10], ketones [11], esters [12], [13], aliphatic, and aromatic hydrocarbons [14]- [16] have been used for extraction of phenol from water.…”

Abstract-This study demonstrates experimental solubility and tie-line data for the (water + phenol + isobutyl acetate) system at T = 308.2 K and atmospheric pressure. This ternary system exhibits type-2 behavior of LLE. To evaluate the extracting capability of the solvent, distribution coefficients and separation factors were calculated. The consistency of the experimental data was determined through the Othmer-Tobias and Bachman equations. The experimental data were correlated using the NRTL and UNIQUAC models, and binary interaction parameters were obtained. The average root mean square deviation values between the experimental and calculated data show the capability of these models.

“…For treating high concentration phenol wastewater (over 1000 mg L −1 ), solvent extraction is a preferred method, and many organic solvents, such as butyl acetate, methyl isobutyl ketone (MIBK), and diisopropyl ether (DIPE), are frequently used to extract the phenols. 2 However, many industrial phenolic wastewaters have very complex compositions that contain polyhydric phenols, such as dihydric and trihydric phenols, with concentrations of hundreds or even thousands of milligrams per liter. These polyhydric phenols are more difficult to extract due to their high affinity for water and low affinity for organic solvents.…”

Liquid−liquid equilibria (LLE) data of the quaternary system {methyl butyl ketone + phenol + hydroquinone + water} and two relevant ternary systems, {methyl butyl ketone + phenol + water} and {methyl butyl ketone + hydroquinone + water}, were measured at T = 313.2 K and p = 101.3 kPa. The experimental data were correlated with the nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) models. The root-mean-square deviation of the NRTL and UNIQUAC models were 0.144 and 0.0476%, respectively. Good agreement was found between experimental LLE data and those calculated from the NRTL or UNIQUAC equations for all systems studied in this work.
