Tuning the properties of ionic liquids by mixing with organic solvents: The case of 1-butyl-3-methylimidazolium glutamate with alkanols

Binary liquid mixtures of 1-butyl-3-methylimidazolium glutamate acid ([bmim][glu]) with alkanols (1-propanol, isobutanol and 1,2-propanediol) are studied in the full composition range as a function temperature using combined experimental computational chemistry approach. Experimental thermophysical information well derived excess mixing properties allowed to characterize these complex terms deviation from ideality their relationships developed intermolecular forces changes type considered alkanols. Theoretical studies quantum classical molecular dynamics simulations provided nanoscopic characterization on fluids, particular attention extension nature hydrogen bonding its effects arrangements mixed fluids’ properties. The reported study provides micro macroscopic aminoacid-based ionic mixtures, thus contributing knowledge sustainable systems organic solvents for fine tuning developing task specific applications.
