1-Methyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide, CAS: 216299-72-8

Key Applications:

Electrochemical Systems and High‑Performance Lithium Metal Batteries

• Serves as a non‑volatile, non‑flammable electrolyte component for lithium metal batteries, improving safety and cycle life.
• Enhances ionic conductivity and SEI stability in high‑energy‑density systems used in electric vehicles and renewable‑energy storage infrastructure.
• Compatible with high‑voltage cathode chemistries due to the wide electrochemical stability window of the TFSI anion.
• Reduces dendrite formation on lithium metal surfaces, supporting next‑generation solid‑state and hybrid electrolyte designs.

Phenolic Compound Extraction and Water Purification

• Selectively extracts phenolic pollutants (phenol, cresols, chlorophenols) from industrial wastewater streams.
• Hydrophobicity and tunable solvation enable high distribution coefficients and efficient phase separation.
• Supports multi‑cycle extraction processes with minimal degradation, making it suitable for continuous purification systems.
• Useful in advanced water‑treatment modules where low volatility and chemical stability are required.

Azeotropic and Difficult Mixture Separation

• Breaks azeotropes by altering relative volatilities through strong, selective solvation of target components.
• Effective in separating alcohol–water, aromatic–aliphatic, and other industrially relevant azeotropic systems.
• Enables energy‑efficient extractive distillation, reducing thermal load and improving separation purity.
• Useful in solvent recovery, fine‑chemical purification, and biomass‑derived feedstock upgrading.

Catalysis and Reaction Media

• Provides a stable, non‑volatile medium for acid‑, base‑, and metal‑catalyzed transformations.
• Enhances selectivity in alkylation, oxidation, and coupling reactions due to strong ion–dipole interactions.
• Supports biphasic catalysis where easy product–catalyst separation is required.

Materials Science and Polymer Processing

• Acts as a plasticizer or conductivity enhancer in polymer electrolytes, ion gels, and flexible electronics.
• Useful in dispersing nanomaterials such as graphene, CNTs, and metal oxides due to strong π–cation interactions.
• Improves thermal stability and ionic mobility in advanced composite materials.

Gas Absorption and Separation

• Demonstrates selective solubility for gases such as SO₂, CO₂, and H₂S.
• Supports membrane‑based separations and gas‑capture systems where chemical stability is essential.

Tribology and High‑Temperature Lubrication

• Functions as a high‑temperature, low‑volatility lubricant or lubricant additive.
• Reduces wear and friction in metal–metal and metal–ceramic interfaces under extreme conditions.

Electrodeposition and Surface Engineering

• Provides controlled metal deposition environments for Cu, Ni, and noble metals.
• Enables smooth, uniform coatings with reduced dendritic growth.
