Uses

Used in Chemical Research:
1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide, 99% [EMIBETI] is used as a model ionic liquid for the preparation of supported ionic liquid membranes (SILMs). These membranes are employed in the studies of CO2 and N2 gas permeation, providing insights into the separation and purification of gases.
Used in Solubility and Absorption Studies:
1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide, 99% [EMIBETI] is used as a medium for the studies of solubility and absorption of 1,1,1,2-tetrafluoroethane, difluoromethane, and fluorinated ethanes in ionic liquids. This helps in understanding the interactions between ionic liquids and various gases, which is crucial for the development of efficient gas separation and absorption processes.
Used in Electro-polymerization Processes:
1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide, 99% [EMIBETI] is used as a medium for the electro-polymerization of pyrrole-based monomers. This process yields N-(methyl)phenyl polypyrroles, which have potential applications in various fields such as sensors, batteries, and fuel cells. The use of EMIBETI as a medium allows for better control over the polymerization process and improved properties of the resulting polymers.

Exploring the effect of fluorinated anions on the CO2/N2 separation of supported ionic liquid membranes

The CO2 and N2 permeation properties of ionic liquids (ILs) based on the 1-ethyl-3-methylimidazolium cation ([C2mim]+) and different fluorinated anions, namely 2,2,2-trifluoromethylsulfonyl-N-cyanoamide ([TFSAM]-), bis(fluorosulfonyl) imide ([FSI]-), nonafluorobutanesulfonate ([C4F9SO3]-), tris(pentafluoroethyl)trifluorophosphate ([FAP]-), and bis(pentafluoroethylsulfonyl)imide ([BETI]-) anions, were measured using supported ionic liquid membranes (SILMs). The results show that pure ILs containing [TFSAM]- and [FSI]- anions present the highest CO2 permeabilities, 753 and 843 Barrer, as well as the greatest CO2/N2 permselectivities of 43.9 and 46.1, respectively, with CO2/N2 separation performances on top of or above the Robeson 2008 upper bound. The re-design of the [TFSAM]- anion by structural unfolding was investigated through the use of IL mixtures. The gas transport and CO2/N2 separation properties through a pure [C2mim][TFSAM] SILM are compared to those of two different binary IL mixtures containing fluorinated and cyano-functionalized groups in the anions. Although the use of IL mixtures is a promising strategy to tailor gas permeation through SILMs, the pure [C2mim][TFSAM] SILM displays higher CO2 permeability, diffusivity and solubility than the selected IL mixtures. Nevertheless, both the prepared mixtures present CO2 separation performances that are on top of or above the Robeson plot.

Dissolution of oligo(tetrafluoroethylene) and preparation of poly(tetrafluoroethylene)-based composites by using fluorinated ionic liquids

Fluorophilic ionic liquids (ILs) showing enhanced compatibility with poly(tetrafluoroethylene) (PTFE) have been newly synthesised. The as-designed ILs contributed both to the dissolution of PTFE oligomers and to the preparation of composites with PTFE with no fear of bleed-out of the ILs.

FLUORINE-CONTAINING N-ALKYLSULFONYLIMIDE COMPOUND, MANUFACTURING METHOD THEREFOR, AND METHOD OF MANUFACTURING AN IONIC COMPOUND

According to the method for producing fluorine-containing N-alkylsulfonylimide compound, the fluorine-containing N-alkylsulfonylimide compound can be produced safely with a high recovery rate by alkylating fluorine-containing sulfonylimide acid or fluorine-containing sulfonylimide acid salt with dialkylsulfuric acid or dialkylcarbonic acid.
