Thermodynamic Modeling of Pseudoternary Aqueous Two Phases Systems With Deep Eutectic Solvents

Abstract

Liquid-liquid equilibrium (LLE) data used in this work were previously obtained by our group research. The quaternary systems were composed to cholinium chloride: glucose + poly(propylene)glycol (400 gmol-1) + H2O at 298.15 K. The Non-Random Two-Liquid (NRTL) model has been used to fit the DES-based aqueous two-phase systems. The interaction parameters of the models were estimated. The liquid−liquid equilibrium (LLE) experimental data were well correlated to the activity coefficients of the NRTL model, and the mean deviations were less than 1,1%.
