“…Wastewater containing such a high concentration of phenol must be pretreated to reduce phenolic content before the wastewater flows into the biochemical treatment section . For removing and recycling phenol from wastewater, solvent extraction is one of the most effective and economical methods to deal with it. − The extraction process can be carried out continuously or intermittently, and the amount of treated water is relatively large.…”

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.

“…The key problem to design a liquid-liquid extraction process is to develop an appropriate extractant with low water solubility, low price and high efficiency to separate cresols from water. However, such study or data is quite scarce at present, with just a few solvents (or extractants) having been reported [20][21][22][23][24]: at 298.2 K, the distribution coefficient (D) and selectivity (S) of methyl tert-butyl ether for cresols are 800~1200 and 3500~13700, those of methyl isopropyl ketone are 390~1450 and 1300~7800 and those of methyl propyl ketone are 530~1450 and 1900~8900. As a polar organic solvent, Mesityl oxide have shown high efficiency in extracting phenol from the aqueous solution [26].…”

In this work, liquid-liquid equilibrium (LLE) data for the ternary systems, mesityl oxide + o-, m-, p-cresol + water, were determined at 333.2 K and 353.2 K under 101 kPa. The high distribution coefficient and selectivity calculated by the experimental tie-line data indicate excellent efficiency for mesityl oxide extracting cresols from aqueous solutions. The NRTL and UNIQUAC models were used to correlate the experimental LLE data, with root mean square deviations (RMSDs) below 2.1% and 1.5%, respectively. The COSMO-SAC model was also employed to calculate the LLE data, which agreed with the experimental results quite well.

“…Hence, quite a few studies have been performed for such purpose. Lv et al reported the LLE data of ternary systems (methyl butyl ketone (MBK) + cresols + water) at (298.2 and 313.2) K. LLE data for the ternary systems methyl isobutyl ketone (MIBK) + o - or p -cresol + water, butyl acetate + o - or p -cresol + water, and isoamyl acetate + o - or p -cresol + water at 303.2 K were published by Telkikar et al Luo et al − studied the LLE of ternary systems of methyl tert -butyl ether + o -, m -, p -cresol + water, and Martin et al studied the water + o -, m -, or p -cresol + heptane or octane systems. Among these extractants, MIBK has been used in some industrial plants.…”

Liquid–Liquid Equilibrium for the Ternary Systems Methyl tert-Butyl Ketone + o-, m-, p-Cresol + Water at (298.2, 313.2, and 323.2) K

Liquid−liquid equilibrium (LLE) for the methyl tert-butyl ketone (MTBK) + o-, m-, and p-cresol + water ternary systems, at temperatures of (298.2, 313.2, and 323.2) K and 101 kPa, were determined in this work. High distribution coefficient and selectivity values were calculated from the LLE data, which indicated that MTBK extracted cresols from wastewater with high efficiency. MTBK also has good physical properties (e.g., low solubility in water, suitable boiling point). The experimental results were regressed and correlated by the NRTL and UNIQUAC activity coefficient models, which both predicted LLE data in close agreement with experiments with RMSD below 3.5%. The corresponding binary interaction parameters were also regressed by these two models, which would be useful for separation process designing or optimizing.
