ABSTRACT
In this work, two ionic liquids 1-ethyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide, [EMpy][NTf2], and 1-methyl-3-propylpyridinium bis(trifluoromethylsulfonyl)imide, [PMpy][NTf2], were investigated as possible solvents in the extraction processes for the ethanol removal from its mixtures with heptaneandhexane. Hence, the experimental determinationof the (liquid + liquid) equilibrium (LLE) for the ternary systems {heptane (1) + ethanol (2) + [EMpy][NTf2] (3)}, {hexane (1) + ethanol (2) + [EMpy][NTf2] (3)}, {heptane (1) + ethanol (2) + [PMpy][NTf2] (3)} and {hexane (1) + ethanol (2) + [PMpy][NTf2] (3)} at T = 298.15 Kandatmospheric pressurewascarried out.Thesolute distribution ratioandselectivitywerecalculated to evaluate the capability of these ionic liquids for the extraction of ethanol. Moreover, comparisons withother ILs takenfromthe literatureweremade.Finally, the experimental LLE valueswerecomparedwith the correlated values obtained by means of the NRTL thermodynamic model.
