Volumetric and viscosity properties of dicationic ionic liquids in (glucose + water) solutions at T = 298.15 K

Apparent molar volumes V Φ ,DIL and viscosity B -coefficients of the dicationic ionic liquids (DILs) in {glucose (Glc)   +   water} solutions were determined from density and viscosity measurements at T   =   298.15   K. Limiting apparent molar volumes V Φ ,DIL 0 of the DILs, volumetric interaction parameters, and activation energies Δ μ DIL 0 ≠ were also obtained, together with the contributions of the solvent property B 1 and the dicationic ionic liquid   –   solvent interaction B 2 to the B -coefficient. A linear relation was observed between V Φ ,DIL 0 and the number of methylene groups n (CH 2 ) in the alkyl linkage chain of DILs. Volumetric interaction parameters and B 2 values are positive and increase with increasing the length of alkyl linkage chain of the dication. The DIL   –   glucose interactions were discussed in terms of the size and solvation of the DILs and glucose.
