Investigation of Volumetric Properties and Taste Behavior for the Ternary{Ionic Liquid (1-Butyl-3-Methylimidazolium Tetrafluoroborate [Bmim][BF4]) + Galactose/Xylose plus Water} Systems at T=293.15 to 313.15 K

摘要

In continuation of our previous research on aqueous systems containing ionic liquids and saccharides, we focus on the ternary {ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4]) + galactose/xylose + water} mixtures. For this purpose, from measured density data, apparent molar volumes V-phi, apparent specific volumes,V-as, apparent molar volumes at infinite dilution V-phi(o), transfer volumes Delta V-t(phi)o and also apparent molar expansibility E-phi(o) for 1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4]) in aqueous galactose or xylose solutions have been calculated. By using these properties, we describe the solute-solute and solute-solvent interactions which exist in these systems, and also the effect of IL [Bmim][BF4] on taste behavior of aqueous galactose and xylose solutions that are mainly discussed in the present research.
