1-ETHYL-3-METHYLIMIDAZOLIUM BIS(TRIFLUOROMETHYLSULFONYL)IMIDE Usage And Synthesis

Description

It is a typical ionic liquid usually used as the solvent in the organic synthesis and chemical industry. For example, this chemical can act as the solvent for dissolving CO2 gas.¹ This substance may also function as the solvent for dissolving the electroactive oxygen, thus allowing for the study of electrochemical reduction of oxygen by cyclic voltammetry at a gold microdisk electrode.² Moreover, determination of ammonia based on electro-oxidation of hydroquinone has been carried out by using this compound as the solvent.³ Besides, nanoparticles of ZnO with the wurtzite structure have been synthesized via a microwave through the decomposition of zinc acetate dihydrate in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide as a solvent.⁴

General Description

1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [EMIM][N(Tf)₂] is a room temperature ionic liquid (RTIL). ([EMIM][N(Tf)₂]) as a non-aqueous solvent, is advantageous over traditional aprotic polar organic solvents in electrochemical investigation of electroactive species since it has low vapor pressure, high thermal stability, good conductivity and a wide electrochemical window. [EMIM][N(Tf)₂] shows good solubility in CO₂.
