Application

1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide can be used:
  • As a model ionic liquid in the preparation of supported ionic liquid membranes (SILMs), which are employed in the studies of CO2 and N2 gas permeation.
  • In the studies of solubility and absorption of 1,1,1,2-tetrafluoroethane, difluoromethane, and fluorinated ethanes in ionic liquids.
  • As a medium for the electro-polymerization of pyrrole based monomers to yield N-(methyl)phenyl polypyrroles.

Physical form

fluorinated, hydrophobic ionic liquid

Other Notes

Novel ionic liquid which is exremely hydrophobic, has improved thermal stability and shows no reactivity towards water or air
