Low-Viscous,Low-Melting,Hydrophobic Ionic Liquids;1-Alkyl-3-methylimidazolium Trifluoromethyltrifluoroborate

摘要

New hydrophobic ionic liquids,l-alkyl-3-methylimidazoli-um (alkyl=methyl,ethyl,n-propyl,n-butyl,n-hexyl) trifluoro-methyltrifluoroborate ([CF_3BF_3]~-),have been synthesized by a metathesis reaction between 1-alkyl-3-methylimidazolium hal-ide and KLCF_3BF_3].All these new ionic liquids exhibit low viscosities (26-77 cP at 25degC) and low melting points,resulting in high conductivities correspondingly.
