N-butylpyridinium bis-(trifluoromethylsulfonyl)imide ionic liquids as solvents for the liquid–liquid extraction of aromatics from their mixtures with alkanes: Isomeric effect of the cation

(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].…”

“…Moreover, some of them are greatly affected by water and other impurities which modify their physical properties [34]. The current trend toward more stable and pure ILs justifies the use of bis(trifluoromethylsulfonyl)imide as the anion for this solvents in liquid-liquid extraction of aromatics [11,12,[30][31][32].…”

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.…”

Prediction of liquid–liquid equilibrium behavior for aliphatic+aromatic+ionic liquid using two different neural network-based models

“…In this regard, 340 experimental data sets were collected and used in developing of the models, helping to propose models with comprehensive application [4,[19][20][21][22][23][24][25][26][27][28][29][30][31]. The high quantity of experimental data sets ensured the comprehensive application of the designed models.…”
