A vibrating-tube digital density meter and a capillary viscometer were used for density and viscosity measurements, respectively. The trends in densities and viscosities with respect to composition and temperature were compared. In addition, excess molar volumes and viscosity deviations were calculated to investigate the molecular interaction between an ionic liquid and an organic solvent. The ability of hydrogen bonding formation and interstitial accommodation were investigated to clarify the influence of excess molar volumes and viscosity deviations. In addition, the obtained excess molar volumes and viscosity deviations were fitted using a four-parameter Redlich-Kister equation. The optimally fitted parameters are presented. The correlated results were consistent with the experimental data. ? 2016. |
