Effect of choline chloride/urea deep eutectic solvent as green and sustainable solvents on conductivity of aqueous sugar solutions

Deep eutectic solvents (DESs) have recently received a great interest in diverse fields due to their unique properties as new green solvents. In this paper, we studied the effect of choline chloride (ChCl)/urea on conductivity of aqueous fructose solutions at (288.15-308.15) K. The physical properties such as conductivity, limiting molar conductivities, , and ion association constants, Ka, for the fructose in aqueous DES solutions have been estimated using low concentration Chemical Model (lcCM).
