Densities, Refractive Indices, Viscosities, and Conductivities of Non-Imidazolium Ionic Liquids [Et3S][TFSI], [Et2MeS][TFSI], [BuPy][TFSI], [N8881][TFA], and [P14][DCA]

Data for the transport properties electrical conductivity, κ, and dynamic viscosity, η, as a function of temperature is presented for non-imidazolium ionic liquids [Et3S][TFSI], [Et2MeS][TFSI], [BuPy][TFSI], [N8881][TFA], and [P14][DCA]. Electrical conductivity has been studied in the wide temperature range of (238.15 to 468.15) K whereas η was determined for (278.15 to 408.15) K. The data could be well fitted by the empirical Vogel–Fulcher–Tammann equation. Additionally, the densities, ρ, and (except for [N8881][TFA]) refractive indices, nD, of these ionic liquids were collected from (278.15 to 363.15) K and (283.15 to 343.15) K, respectively. Both properties exhibited a linear variation with temperature. The data obtained suggest that IL [P14][DCA] is unstable.
