Solvation behaviour and partial molar properties of monosaccharides in aqueous protic ionic liquid solutions

Volumetric properties of 1-butyl-3-methylimidazolium bromide in aqueous solutions of d(−)-ribose and d(−)-arabinose at different temperatures

“…Table S1). The density of [Bmim]Br in water at (298.15, 308.15 and 318.15) K agrees well with already reported values [43], similarly the density of Rib and Arb in water at (288.15, 298.15, 308.15 and 318.15) K agrees well with literature values [44][45][46]. The density of binary ([Bmim]Br + water) ( The apparent molar volumes, V 2,ϕ of [Bmim]Br in water and in aqueous solutions of Rib and Arb at different temperatures and at atmospheric pressure (Supporting information Table S1) were evaluated from experimentally determined density, ρ by using the following equation:…”

“…Banipal et al [45] have also reported higher Δ t V 2°v alues of Rib as compared to other monosaccharides in presence of sodium acetate. Recently, positive Δ t V 2°v alues of some monosaccharides (glucose and ribose) and disaccharides (sucrose) in presence of ammonium based protic ionic liquid [46,50], and also for sucrose in aqueous 1-allyl-3-methylimidazolium chloride [51] and 1-butyl-3-methylimidazolium tetrafluoroborate [52] solutions have been reported, which further strengthens the view that the dominance of hydrophilic-ionic type of interactions contribute positive to transfer volumes. The electrical conductivity of imidazolium based ILs in aqueous solution of D-xylose has been studied and it was reported [23] that with addition of ILs to aqueous solutions of monosaccharides strengthens the solute-cosolute interactions.…”

Effect of protic ionic liquid on the volumetric properties of ribose in aqueous solutions

“…Furthermore, absolute understanding of molecular interactions between ILs and saccharides in mixed aqueous solutions demands more accurate determination of thermophysical properties [32,34]. Further, it has been reported that the capability of an IL for biomass processing depends upon the hydrogen bond accepting ability of the anionic part of IL [34]. So, in this work we report the volumetric and ultrasonic properties of a monosaccharide D(À)-ribose (Rib) in aqueous solutions of ammonium based protic ionic liquid (PIL) as a function of concentration and temperature.…”

Apparent molar volume, conductivity, and fluorescence studies of ternary systems of dipeptides + ionic liquids ([Cnmim]Br, n = 10, 14) + water at different temperatures

“…However, for more complex systems including biomolecules such as proteins, nucleic acids, saccharides, and so on, experimental measurements on their physicochemical properties are still scarce because of the complex configurational and conformational aspects of macromolecule structure in aqueous solution. There have been some investigations on the interaction of ILs with some small biomolecules, such as amino acids [5][6][7][8] and monosaccharides [9][10][11]. However, to the best of our knowledge, few reports [12] are available in the literature on the interactions of some small peptides with ILs in aqueous solutions at different temperatures.…”
