Abstract

A new room temperature molten salt (room temperature ionic liquid), 1-ethyl-2,3-dimethylimidazolium fluorohydrogenate (EDMIm(HF)_2.3F), has been prepared by the reaction of EDMImCl and large excess of anhydrous hydrogen fluoride (aHF). EDMIm(HF)_2.3F is composed of EDMIm cation and (HF)_nF anions (fluorohydrogenate anions) and exhibits the conductivity of 56.9 mS cm⁻¹ and viscosity of 6.8 cP at 298 K. Electrochemical window of EDMIm(HF)_2.3F determined by cyclic voltammetry using a glassy carbon electrode as a working electrode is about 2.9 V that is close to the window of 1-ethyl-3-methylimidazolium fluorohydrogenate (EMIm(HF)_2.3F) reported previously.
