ABSTRACT

The density and viscosity of binary ionic liquid mixtures with a common anion, 1-ethyl-3-methylimidazolium tetrafluoroborate + 1-propyl-3-methylimidazolium tetrafluoroborate, 1-ethyl-3-methylimidazolium tetrafluoroborate + 1-propyl-3-methylimidazolium tetrafluoroborate, and 1-propyl-3-methylimidazolium tetrafluoroborate + 1-hexyl-3-methylimidazolium tetrafluoroborate were determined in the temperature range of (298.15 to 343.15) K. The excess molar volumes were calculated and correlated by Redlich Kister polynomial expansions. The viscosities for pure ionic liquids were analyzed by means of the Vogel Tammann Fulcher equation, and ideal mixing rules were applied for the mixtures.
