Abstract
Abstract Transport properties of selected imidazolium ionic liquids (1-ethyl-3-methylimidazolium acetate, [emim][ac], and 1-butyl-3-methylimidazolium trifluoromethanesulfonate, [bmim][triflate]) as well as of binary mixtures of these ILs with water and ethanol were estimated experimentally. Density data were obtained within the temperature range of 293.15—333.15 K and used for the excess molar volume calculations. For the binary mixtures comprising selected ionic liquids and water/ethanol, partial molar volumes of mixture components were computed and the excess molar volume variation with the mixture composition was correlated using the Redlich-Kister equation. Dependence of viscosity on the binary mixture composition and temperature was described using the Jouyban-Acree model. These data form a base for the assessment of OPEX connected with transportation of mixtures containing these ionic liquids.
