“…Phenol-containing wastewater mainly comes from chemical industries such as coking plants, gas plants, petrochemical plants, and insulating materials plants. , The concentration of phenolic substances in wastewater generated from the Lurgi gasification process is very high, and treating 1 ton of coal will produce about 0.8–1.1 tons of phenol-containing wastewater. , Phenol has germicidal activity and degrades protein . Wastewater containing such a high concentration of phenol must be pretreated to reduce phenolic content before the wastewater flows into the biochemical treatment section .…”

1-Dodecanol with low solubility in water is a potential solvent to extract phenol from wastewater. The liquid–liquid equilibrium data of the ternary system (1-dodecanol–phenol–water) were measured at 298.15, 313.15, 323.15, 333.15, and 343.15 K under atmospheric pressure. The experimental data were correlated by the nonrandom two liquids (NRTL) and universal quasi-chemical (UNIQUAC) models, and the corresponding binary parameters were obtained. The results show that the two models agree well with experimental values. Comparison of the average values of the root mean squared deviation (RMSD) from both models reveals that the NRTL model is more accurate than the UNIQUAC model. The effect of temperature on the extraction process is discussed, and temperature has little effect on extraction efficiency. The van’t Hoff equation is used to correlate the relationship of distribution coefficient to temperature. The enthalpy change of the extraction process was calculated, and the result shows that extraction of phenol from water by 1-dodecanol is an exothermic process.

“…Mixtures of chloroform with other solvents (toluene or diethyl ether) were also used to separate ethanol from water. 41,48 To select a proper solvent for the separation process using liquid−liquid extraction, 13 parameters could be considered: separation factor (1), distribution coefficient (2), insolubility of solvent in raffinate (3), recoverability (4), density (5), interfacial tension (6), chemical reactivity (7), viscosity (8), vapor pressure (9), freezing point (10) non-toxicity (11), nonflammability (12), and low cost (13). 49 Chloroform and carbon tetrachloride have 10 options out of 13 (1,3,4,5,6,7,8,10,12,13).…”

“…In this work, two chlorinated methanes (tri and tetra chloromethane) were chosen as solvents to investigate the liquid–liquid equilibria of ternary systems (water + OPA + chloroform) and (water + OPA + carbon tetrachloride). Some authors have already reported LLE data for the systems consisting of chloroform and carbon tetrachloride. − Acetone, nicotine acetic acid, , and tetrahydrofuran were purified using carbon tetrachloride and acetic acid, ,, while tetrahydrofuran, valeric acid, pyruvic acid, propionic acid, acetyl acetone, and 2-methylaziridine were separated using chloroform. Mixtures of chloroform with other solvents (toluene or diethyl ether) were also used to separate ethanol from water. , …”

In the present study, phase equilibrium data of the systems (water + orthophosphoric acid + chlorinated methanes) were measured in the temperature range of 298.2−318.2 K under ambient conditions. Chloroform and carbon tetrachloride were chosen as chlorinated solvents. Both the systems exhibited a type II phase behavior. The presence of hydrogen atoms in chloroform caused differences in phase behavior, partition coefficients, and solubility of the acid in the studied chlorinated methanes. Solid orthophosphoric acid was dissolved six times more in chloroform than in carbon tetrachloride. The thermodynamic modeling was conducted using the NRTL and UNIQUAC equations. Root mean square deviations were calculated to assess the quality of correlations, and the values were lower than 1% for UNIQUAC and 2% for NRTL models. The binary interaction parameters were optimized, and the temperature dependency of the binary parameters was considered. The performance of the studied solvents was evaluated by calculating the distribution coefficients (0.007 to 0.032 for chloroform and 0.004 to 0.008 for tetrachloromethane as solvents) and separation factors (9.81 to 1.25 for CHCl 3 and 5.67 to 1.70 for CCl 4 solvent systems) over the immiscibility region. Temperature increment had obvious effects on the partition coefficients of chloroform ternary mixtures. The obtained partition coefficients at 298.2 K were eventually regressed using the Catalań linear solvation energy relationship (LSER) model. The LSER modeling proposed that polarizability and dipolarity have large negative and positive effects on the distribution coefficient, while acidity and basicity have small and very small positive effects, respectively. LSER modeling of separation factors suggested polarizability as the strongest positive function and basicity as a negative one.
