Liquid–Liquid Equilibrium for Ternary Systems of 2-Pentanone/Mesityl Oxide + Catechol + Water at 298.2, 318.2, and 333.2 K

Abstract: Liquid−liquid equilibrium (LLE) data for the ternary system of (2-pentanone + catechol + water) and (mesityl oxide + catechol + water) was measured under atmospheric pressure at T = (298.2, 318.2 and 333.2) K. The distribution coefficients and separation factors were employed to assess the efficiency of extracting catechol from water. The nonrandom two liquid and universal quasichemical models were applied to correlate the LLE data, and the corresponding binary interaction parameters were obtained. The topolog… Show more

“…The points of the aqueous phase are concentrated in the lower left area of the diagram, and the points of the organic phase are basically distributed in the right side of the diagram. A comparison of the phase diagrams for MPK + resorcinol/hydroquinone/catechol + water at 333.15 K under 101.3 kPa in this work with those in ref and ref was shown in Figure S1. As shown in Figure S1, deviations for the (pentan-2-one + resorcinol + water) and (pentan-2-one + hydroquinone + water) systems are extremely small.…”

“…Chen et al studied the impact of carbon chains including C–C or CC bonds on the polarity of a molecule and revealed that the polarity of a molecule containing a CC bond is higher than that containing a C–C bond. In addition, MO tends to represent a high distribution coefficient toward catechol. However, MO is an α, β-unsaturated carbonyl compound and shows higher reactivity than ordinary solvents of liquid extraction fields. Then, it is necessary to determine the limitations of using MO in liquid–liquid equilibrium studies.…”
