Thermodynamic Behaviour Of Lithium Chloride Solutions Containing Deep Eutectic Solvent In The Dilute Region At T = (288.15 to 303.15) K

Deep eutectic solvents (DESs) have getting a much attention in many areas of science and technology in the last decade. In this respect we have studied thermodynamic behaviour of aqueous Lithium Chloride solution + Deep Eutectic Solvent in the dilute region at different temperatures (T=288.15-318.15 K) under atmospheric pressure (≈ 85 kPa). To obtain some information regarding the solute-solvent interaction in this system the densities (d) were measured for Lithium Chloride aqueous solutions of the DESs based on choline chloride (ChCl) with urea. On the basis of calculated apparent molar volume values calculated from the measured density data, solute-solvent and solvent-solvent interactions are discussed.
