N2 - Deep eutectic solvents (DESs) formed by cholinechloride and urea or glycerol were tested for the separation ofazeotropic mixtures. The case study was the separation of ethanol−ethyl propionate and n-propanol−n-propyl propionate. For thisaim, the experimental data of liquid−liquid equilibria (LLEs) wereobtained at temperature 293.15 K and atmospheric pressure.Liquid−liquid tie lines were determined using NMR spectroscopyand analyzed. The extraction performance of DESs wascharacterized with distribution coefficients and values of selectivityto alcohol. Comparison of selectivity values in systems containingalcohols and esters with another DES formed by choline chloride and malonic acid was carried out. The NRTL model for LLE datacorrelation was used. The model is shown to give rather good estimates for the selectivity values.
