Liquid-Liquid Equilibria for the Three Ternary Systems (3-Methyl-N-butylpyridinium Dicyanamide plus Toluene plus Heptane), (1-Butyl-3-methylimidazolium Dicyanamide plus Toluene plus Heptane) and (1-Butyl-3-methylimidazolium Thiocyanate plus Toluene plus Heptane) at T = (313.15 and 348.15) K and p=0.1 MPa

Liquid-liquid equilibrium data for the ionic liquids 3-methyl-N-butylpyridinium dicyanamide ([3-Mebupy][DCA]), 1-butyl-3-methylimidazolium dicyanamide ([BMIM][DCA]), and 1-butyl-3-methylimidazolium thiocyanate ([BMIM][SCN]) with toluene and heptane were investigated at T = (303.15 and 328.15) K and atmospheric pressure. The experimental data were regressed and could be correlated adequately with the nonrandom two-liquid model. The results show that the extraction capacity of the three investigated ionic liquids is in the order of: [3-Mebupy][DCA] > [BMIM][DCA] > [BMIM][SCN].
