Electrical conductivity property of binary systems composed of N-butyl-3-methyl pyridinium bis（trifluoromethylsulfonyl） imide and alcohols solvents
Abstract：A novel hydrophobic ionic liquid N-butyl-3-methyl pyridinium bis（trifluoromethylsulfonyl）imide（[C4M3Py][NTf2]） is synthesized and characterized.The electrical conductivities of three binary sys-tems composed of the ionic liquid and methanol,ethanol,and isopropanol are determined respectively.The re-sults show the electrical conductivities of the binary systems are greater than that of the pure ionic liquid and thestrength sequence of the conductivities is： k（[C4M3Py][NTf2]＋ methanol） k（[C4M3Py][NTf2 ＋ etha-nol） k（[C4M3Py][NTf2 ＋ isopropanol）.The relationship between the ionic liquid concentrations and theconductivities of the mixed systems is described by an empirical Castell-Amisequation.
