“…Diisopropyl ether also performs better than most of the solvents (except octan-1-ol) in a very recent study, whose distribution coefficients are usually no more than 23.66, selectivities are no more than 180.75. Furthermore, diisopropyl ether have been used to extract other pollutants, such as phenol and propionic acid, with excellent performance.…”

“…Also, the distribution coefficient and selectivity are the most important values when selecting solvent since they reveal the separating power of a solvent. In some previous literature, diisopropyl ether (DIPE) was widely used as solvent to extract acetic acid, propionic acid, and phosphoric acid, and so forth. We also compared the other solvents and found that DIPE may be a promising solvent for the butyric acid recovery. ,− In addition, DIPE has a lower solubility, viscosity, and density .…”

In this work, liquid−liquid equilibrium (LLE) data for ternary system water + butyric acid + diisopropyl ether (DIPE) at atmospheric pressure and temperatures of 298.15 K, 313.15 K, and 323.15 K were experimentally measured. From the resulted distribution coefficient and selectivity, we can find that diisopropyl ether is an efficient solvent to extract butyric acid. The reliability of the experimental tie-line data was ascertained through the Othmer−Tobias and Hand equations. The consistency of experimental tie-line data was confirmed by the NRTL and UNIQUAC models. Both models describe the phase behavior of the studied systems accurately with very small average deviations.

“…Consequently, separation of this acid from aqueous solutions is an economically and environmentally crucial issue. In the earliest investigations, several authors have reported many LLE data on systems containing water, PA, and organic solvents from different chemical categories. − Subsequently, important studies have been carried out on the acid extraction from water and LLE measurements by several researchers. − Mainly, hydrocarbons and halogenated hydrocarbon, − ketones, − heavy alcohols, − esters and dibasic esters, − nitriles, , and ethers have been examined for the LLE measurements. In the latest investigations, Özmen and co-worker have reported further equilibrium data for the related PA containing systems.…”

This paper reports the ternary liquid−liquid equilibrium (LLE) data for water−propionic acid−ethylbenzene at T = (308.2 and 318.2) K and water− propionic acid−benzyl benzoate systems at T = (298.2, 308.2, and 318.2) K and p = 0.1 MPa for the first time. Solubility data and mutual solubilities between ethylbenzene or benzyl benzoate and water were measured using the traditional cloud point method. Tie lines were experimentally obtained using acidimetric titration, the Karl Fisher titration and the refractive index measurements on the both aqueous and organic phases. The ternary systems exhibit type-1 phase behavior. The reliability of the tie-line data exhibited linear behavior in the Hand and Othmer−Tobias correlation plots. The experimental tie line data were correlated using the nonrandom two-liquid and universal quasichemical thermodynamic models, and the corresponding binary interaction parameters were determined. The results demonstrate the capability of the two models in correlation and description of the phase behavior of the related ternary systems with acceptable average root-mean-square deviation (rmsd) values. As a result, temperature has only a minor effect on the LLE behavior of the system containing benzyl benzoate.

Influence of Salt on the Solubility and Tie-Line Data for Water + Formic Acid + Methyl Isobutyl Ketone at T = 298.15 K

et al. 2016

The tie-line and solubility data for the systems containing formic acid (FA), water, and methyl isobutyl ketone (MIBK) + NaCl were determined experimentally at temperature 298.15 K and atmospheric pressure. The effect of salt 0.05−0.15 mass fraction (base on mass of initial water) was investigated. Binary interaction parameters were ascertained by comparing the experimental tie-line data with the nonrandom two-liquid model (NRTL) correlations. The tie-line data of the systems were analyzed using the Othmer−Tobias, Hand, and Bachman correlation equations. Separation factors and distribution coefficients were assessed. The results show that enlargement of the two−-hase region occurred when the concentration of salt increased in the initial aqueous phase; adding salt to the system proved beneficial in separating FA from water.
