| Popis: | 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. |
