AbstractThe functional ionic liquid (FIL) 1-(cyanopropyl)-3-methylinnidazoliumbis(trifluoromethyl)sulfonyl imide PCNMIMNTf2 was synthesized using an ion-exchange method. Density, dynamic viscosity, electrical conductivity, and refractive index were determined in the temperature range 283.15-353.15 K. The effect of methylene group introduction is discussed for the FILs and imidazolium ionic liquids (ILs). The thermal expansion coefficient, molecular volume, standard molar entropy, and lattice energy were determined by the empirical equations from the measurement values. The temperature dependence on electrical conductivity and dynamic viscosity of the FILs were fitted by the Vogel-Fulcher-Tammann (VFT) equation. The adaptability of the Arrhenius equation was also discussed for the electrical conductivity and dynamic viscosity. The study of the thermodynamic properties of the FIL is important for synthesis of new ILs and their application.
