Electrical conductance and solvation of 1-butyl-3-methylimidazolium trifluoromethane sulfonate in propylene carbonate
Abstract
The results of conductometric investigation on 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) in propylene carbonate over the temperature range 5-115°С are presented. By using Lee-Wheaton equation the limiting molar conductivities and parameters of the closest approach for the investigated ionic liquid were determined from experimental conductivity data.
It was established that the studied electrolyte in propylene carbonate is characterized by the absence of the ionic association. Dynamical radii of solvated ions decrease when temperature increases.
