New Ionic Liqiuds with Alkoxymethyl Hydrophobic Groups

Air and water stable new ionic liquids with alkoxymethyl hydrophobic substituents and alkyl group on C(2) in imidazolium cation have been prepared and characterized. 14 tetrafluoroborate salts and 8 hexafluorophosphate salts are liquids at r.t. The properties of obtained salts are reported. The variation of substituents on the imidazolium cation have led to useful trends in the melting point and density and have a significant influence on the thermal stability.
