Abstract:Two novel room-temperature ionic liquids, 1-methyl-3-methylimidazole methyl sulfate and 1-butyl-3-methylimidazole methyl sulfate were formed by the reaction of dimethyl sulfate with methylimidazole and butylimidazole at room temperature respectively. The electrical conductivity of the ionic liquids was also measured at different temperatures. The result showed that the electrical conductivity value increased rapidly along with the temperature rising. And the temperature dependence of the electrical conductivity for all measured ILs can be coincided highly with a four-order polynomial equation and Vogel-Tamman-Fulcher (VTF) equation.
Keywords:dimethyl sulfate  room-temperature ionic liquid  electrical conductivity  Vogel-Tamman-Fulcher equation
