Phase equilibria of toluene/heptane with deep eutectic solvents based on ethyltriphenylphosphonium iodide for the potential use in the separation of aromatics from naphtha

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

“…DES selectivity typically decreases with an increasing concentration of benzene in the raffinate phase. This trend is in agreement with the results reported for other ternary systems involving DESs as extracting solvents [30,42]. Furthermore, the values of selectivities in all ternary systems studied were greater than unity, indicating that extraction is possible.…”

Experimental investigation and modeling of thermophysical and extraction properties of choline chloride + DL-malic acid based deep eutectic solvent

“…Here DES was treated as one component, as it was stated also previously in the literature for other combinations of eutectic mixtures. 10,22 The activity coefficients in NRTL model were calculated using the following equation:…”

Experimental determination of the LLE data of systems consisting of {hexane + benzene + deep eutectic solvent} and prediction using the Conductor-like Screening Model for Real Solvents

“…DESs were found to be alternative solvents in several separation processes, such as CO2 capture 25,26 , biomass treatment 27 and azeotrope breaking via extractive distillation 28 and liquidliquid extraction [29][30][31][32][33][34][35][36] . They have already been successfully applied to the separation of aromatic components from {aliphatic + aromatic} mixtures.…”

“…The separation of {hexane + benzene} mixture was studied using quaternary phosphonium and ammonium salts as HBA 29,35 . Other {aliphatic + aromatic} mixtures (for example {heptane + toluene}) were also studied [32][33][34]36 . Although the results are promising, there is a lack of information regarding the effect of the characteristics of both the HBD and the HBA on the extraction process.…”
