1-Ethyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide

Description:
1-Ethyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, commonly referred to as EMIM TFSI, is an ionic liquid characterized by its low volatility, high thermal stability, and excellent solvation properties. It features a pyrrolidinium cation, which contributes to its ionic nature, and the bis(trifluoromethylsulfonyl)imide anion, known for its strong electrochemical stability. This compound is typically colorless to pale yellow and exhibits a relatively low melting point, making it liquid at room temperature. EMIM TFSI is highly soluble in various polar solvents and is often used as an electrolyte in electrochemical applications, including batteries and supercapacitors, due to its high ionic conductivity. Additionally, it has a wide electrochemical window, which enhances its utility in energy storage systems. Its unique properties also make it a candidate for applications in catalysis and as a solvent for chemical reactions, particularly in green chemistry, where its low volatility reduces environmental impact. Overall, EMIM TFSI is a versatile ionic liquid with significant potential in various fields of chemistry and materials science.
