ABSTRACT

Data for the transport properties electrical conductivity, , and dynamic viscosity, , 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 ? 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, , 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.
