Abstract

The ion assocn. in solns. of 1-N-butyl-3-N-methylimidazolium chloride ([bmim][Cl]) in acetonitrile and in water was studied by dielec. spectroscopy for salt concns. c ≤ 1.3 M at 298.15 K and by measurement of molar elec. conductivities, Λ, of dil. solns. (c ≤ 0.006 M) in the temp. range 273.15 .ltorsim. T/K ≤ 313.15. While acetonitrile solns. of [bmim][Cl] exhibit moderate ion pairing, with an ...
