Estimating VLE behavior from SLE data in aqueous mixtures of choline chloride-sorbitol deep eutectic solvents: Experimental investigation and thermodynamic modeling using the e-NRTL model

Knowledge of solid–liquid equilibria (SLE) and vapor–liquid (VLE) for mixtures containing deep eutectic solvents (DESs) is paramount importance. We have conducted experiments to obtain additional data SLE systems then used the e-NRTL model predict VLE behavior in DESs comprised choline chloride (ChCl), sorbitol (S), water (W). The under investigation include three 2-component (S/W, ChCl/W, ChCl/S), one 3-component system (DES/W) where DES obtained by mixing ChCl S at a molar ratio 1. Using activity coefficient model, adjusted binary interaction parameters proposed are determined solely from experimental this work also those literature. There an excellent agreement between solubility results. tuned bubble pressure aqueous DES/W) with overall AARD value 2.21%. predicted demonstrates viability thermodynamic modelling framework represent equilibrium DESs. outcome our study can be relate without need perform both cases given interest. Compared experiments, tests much simpler safer because there little compressibility effect on minimal which makes it possible conduct room conditions (at least liquids negligible non-ideality). Therefore, conducting high-pressure calculations through alone will practical significance.
