ternary liquid liquid equilibria ethanol 2 Butanone 1 butyl 3 methylimidazolium hexafluorophosphate 2 propanol 2 Butanone 1 butyl 3 methylimidazolium hexafluorophosphate and 2 Butanone 2 propanol 1 3 dimethylimidazolium methyl sulfate at 298 15 k
Journal of Chemical & Engineering Data, 2007Co-Authors: Ana Pereiro B And, Ana RodríguezAbstract:This research is focused on a study of the ionic liquid as a solvent in liquid−liquid extraction of azeotropic mixtures. Liquid−liquid equilibria (LLE) were determined for the ternary systems ethanol + 2-Butanone + 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]), 2-propanol + 2-Butanone + [BMIM][PF6], and 2-Butanone + 2-propanol + 1,3-dimethylimidazolium methyl sulfate ([MMIM][MeSO4]) at 298.15 K and atmospheric pressure. Selectivity and distribution ratio values, derived from the tie lines data, were calculated. Experimental LLE data were correlated by means of the nonrandom two-liquid, Othmer−Tobias, and Hand equations. The plait point compositions have been calculated by the Hand method.

isobaric vapor liquid equilibria in the systems 2 Butanone heptane and 2 Butanone oxolane
Journal of Chemical & Engineering Data, 1998Co-Authors: Jaime Wisniak, Eti Fishman, Rotem ShaulitchAbstract:Vapor−liquid equilibrium at 94 kPa has been determined for the binary systems 2-Butanone + heptane and 2-Butanone + oxolane. The system 2-Butanone + heptane deviates strongly from ideal behavior and presents an azeotrope that boils at 348.4 K and contains 75.0 mol % 2-Butanone. The system 2-Butanone + oxolane behaves like a regular solution and does not have an azeotrope. The activity coefficients and boiling points of both binary systems were well-correlated with its composition by the Redlich−Kister, Wohl, Wilson, UNIQUAC, NRTL, and Wisniak −Tamir equations.

Measurements and correlation of vapour–liquid equilibria of 2-Butanone and hydrocarbons binary systems at two different pressures
Fluid Phase Equilibria, 2011Co-Authors: Estela Lladosa, Nelson F. Martínez, Juan B. Montón, Javier De La TorreAbstract:Abstract Consistent isobaric vapour–liquid equilibrium data have been measured for 2-Butanone + n-hexane, 2-Butanone + n-heptane, and 2-Butanone + 2,2,4-trimethylpentane at two different pressures. All binary systems present a minimum boiling azeotrope at both pressures, and show that the azeotropic compositions are weakly dependent on pressure. The equilibrium data were correlated using the Wilson, NRTL, and UNIQUAC models for which the parameters are reported.
