Imidazolium ionic liquids

List of ionic liquids based on imidazolium cations

Ionic liquids are made up of charged species and imidazolium-based ionic liquids have one of the nitrogen atoms in the imidazolium ring in the cationic form. These are generally synthesized by alkylation of an N-alkylimidazole and further incorporation of the desired anion by anion metathesis. Imidazolium cations are abbreviated as [xyim]+, where x and y are the first letters of the names of the alkyl chains on the nitrogen atoms.  These ionic liquids are used as a reaction media for several organic transformations. They are also used for pretreatment of coal for better gasification and as absorbents in carbon capture. 1-butyl-3-methylimidazolium chloride is used as an electrolyte for the recovery of uranium from spent nuclear fuel. They are the best choice of materials for application in sensors and supercapacitors because of their electrochemical stability.
