New ionic liquids with fluorous anions for supported liquid membranes and characterization

International audienceThis article reports the synthesis and the characterization of novel fluorous ionic liquids with fluorous anions to be used as carrier for fluorous supported liquid membrane in view of future applications to the extraction of metal ions. Dialkylimidazolium perfluorodialkylphosphate with C8, C10 and C12 phosphate chains have been synthetized as ionic liquid. The different dialkylimidazolium cations were prepared by microwave technique. Finally, 1-butyl-3-decylimidazolium di(1H,1H,2H,2H-perfluorodecylphosphate) was found as the most appropriated ionic liquid for the considering application and was characterized with volumetric mass density, viscosity and thermal stability measure
