Separation potential of 1,5-pentanediol-based deep eutectic solvent: Infinite dilution activity coefficients and excess thermodynamic data

“…This is due to the presence of O atoms in these organic solutes, which have significant interactions with the DES components. For alcohols and water, their infinite dilution activity coefficients in the investigated DES are minimal because of the fact that the lone pair electron of the oxygen atom in the hydroxyl group can interact with components in the DES and that acidic protons have a strong binding capacity with halides, making them more soluble in the solvent [ [51] , [52] , [53] , [54] ]. Like the law of alkanes, the intermolecular force of alcohols will increase as the carbon chain length increases, and the force between alcohols and DESs will decrease as a result.…”
