ABSTRACT
Densities of two selected ionic liquids (ILs), 1-butyl-3-methylimidazolium bis(trifluoro-methylsulfonyl)imide, [bmim][NTf2], and 1-butyl-1-methylpyrrolidinium bis(trifluoromethyl-sulfonyl)imide, [bmpyr][NTf2], were determined in the temperature range from (293.15 to 353.15) K. From the experimental density values, the thermal expansion coefficient was calculated. The specific conductivity was measured in the range from (303.15 to 353.15) K. Our experimental results were compared with available literature data. Also, viscosity of these ionic liquids was measured from room temperature up to 353.15 K. Using the obtained data, the temperature effect on the viscosity was analyzed. Since there are limited literature data on physicochemical properties of ionic liquids, data obtained in this study can provide valuable contributions for better understanding of ILs behavior.
