Separation of toluene and heptane by liquid–liquid extraction using z-methyl-N-butylpyridinium tetrafluoroborate isomers (z=2, 3, or 4) at T=313.2 K

(Liquid+liquid) equilibrium for the ternary systems {heptane+toluene+1-allyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide} and {heptane+toluene+1-methyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide} ionic liquids

“…Hence, and as a continuation of our previous work [21,22,[28][29][30][31][32], we have focus our research on the LLE for the ternary systems formed by {toluene + heptane + 1-methyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide ([mpim][Tf 2 N])} and {toluene + heptane + 1-allyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([amim][Tf 2 N])} at 313.2 K and atmospheric pressure. The selectivity and extractive capacity were calculated from the LLE data and were compared with those of sulfolane [6].…”

Efficient removal of benzene from cyclohexane-benzene mixtures using deep eutectic solvents – COSMO-RS screening and experimental validation

“…However, these solvents are typically toxic, flammable, volatile, and difficult to regenerate. In contrast to conventional solvents, ionic liquids (ILs) have been found to be promising solvents for extraction because of their high thermal stability, negligible vapor pressure, nonvolatile nature, and high solution capacity [4,5,[17][18][19]. Several ILs were studied to show good performance in extraction of benzene from cyclohexane including [ [22], and [C n Mim][PF6] (n = 4, 5, 6) [23].…”

Liquid–liquid extraction of aromatics from their mixtures with alkanes using 1-methyl 3-octylimidazolium thiocyanate ionic liquid

“…The separation of toluene and ethyl benzene from hexane, using this IL has been reported by González et al [19]. Garcia et al have reported several experimental data for the LLE of (toluene + heptanes) with different types of pyridinium based ILs [20][21][22]. Meindersma et al [1] have shown that the ILs can be replaced with the conventional solvents in liquid-liquid extraction of aromatic hydrocarbons and evaluated the extraction of aromatics with ILs in industrial processes.…”
