“…Although PILs have a wide potential for industrial uses, their future applications will depend on the understanding of the relation between the molecular-level structure, cooperative dynamics, and macroscopic properties. 48 There are two overlapping topics (ionic liquids and distillation processes), so before the discussion, the authors refer to some theoretical issues.…”

Experimental data on the distillation boundary in the ethyl trifluoroacetate (EtTFA)–trifluoroacetic acid (TFA)–N-methyl-2-pyrrolidone (NMP) azeotropic (Az) system are considered. Theoretical qualitative model of the distillation map of the EtTFA–TFA–NMP mixture at atmospheric pressure supposes two distillation areas with TFA or EtTFA having lower volatility and vice versa, and they are split by the separatrix AzEtTFA/TFA–protic ionic liquid (PIL). From the experimental data, for the liquid phase that is located closer to the center of the concentration simplex, the third component traces occurred, but in general, the vapor-phase composition (vapor line) in the distillation map belongs to binary constituents. One more interesting aspect is the vapor composition line across the binary azeotrope EtTFA–TFA and, as a consequence, the separatrix AzEtTFA/TFA–PIL. Therefore, the separation during Rayleigh distillation and thermodynamic constraint (caused by the presence of the azeotrope and the separatrix generated by it) overcoming become possible by reason of PIL formation.

“…The chemicals and reagents used in this work are shown in Table S1 of Supporting Information (SI) together with the corresponding suppliers and purities. The PILs used in this work were synthesized by a Brønsted-Lowry titration between ethanolamine and the corresponding organic acid (see Table S1 of SI) and were purified as described in literature [8,38]. PILs were dried under vacuum (4 Pa) for at least 48 h with continuous stirring.…”

The aim of this work is to evaluate the separation of hydrocarbons (hexane and heptane) from their azeotropic mixtures with ethanol using protic ionic liquid (PIL) as extraction solvents. With this goal in mind, PILs were synthesized and their thermal and physical characterization were carried out. Experimental determination of the phase equilibrium for the ternary systems hydrocarbons + ethanol + PIL at 298.15 K and 101.2 kPa were also carried out in order to evaluate the feasibility of this application. The solute distribution ratio and the selectivity were also determined to compare the solvent capacity of these PILs. The NRTL equation was used to correlate the experimental data. Furthermore, this paper provides a comparison of the solvent capacity of these PILs with different extraction solvents (ionic liquids (ILs), ILs mixtures and deep eutectic solvents) available in the literature. Then, a critical review for the separation of these azeotropic mixtures was carried out using the extraction processes data obtained through the simulation using a conventional software.
