Abstract

Ion association of the ionic liquid [bmim][Cl] in acetonitrile and in water was studied by dielectric spectroscopy for salt concentrations c <= 1.3 M at 298.15 K and by measurement of molar electrical conductivities, L, of dilute solutions (c <= 0.006 M) in the temperature range 273.15 <= T/K <= 313.15. Whilst acetonitrile solutions of [bmim][Cl] exhibit moderate ion pairing, with an association ...
