Trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide, CAS: 460092-03-9

Key Applications:

1. Electrochemical and Energy Storage Systems

• Serves as a non‑volatile, high‑stability electrolyte component in supercapacitors and high‑temperature batteries.
• Enhances ionic conductivity and thermal endurance in mixed‑solvent or polymer‑gel electrolytes.
• Used as a plasticizing ionic liquid in solid polymer electrolytes to improve mechanical flexibility and ion mobility.

2. High‑Temperature and Extreme‑Environment Lubrication

• Functions as a base fluid or additive in high‑temperature lubricants due to its negligible vapor pressure and oxidative stability.
• Reduces friction and wear in metal–metal and metal–ceramic interfaces under demanding thermal conditions.
• Suitable for aerospace, industrial, and vacuum‑environment lubrication where conventional oils degrade.

3. Phase‑Transfer and Catalytic Media

• Acts as a hydrophobic ionic medium for biphasic catalysis, enabling efficient separation and catalyst recycling.
• Supports organometallic and acid‑catalyzed transformations requiring low coordinating, thermally stable environments.
• Provides tunable solvation for transition‑metal complexes and reactive intermediates.

4. Extraction, Separation, and Hydrophobic Partitioning

• Employed in liquid–liquid extraction of hydrophobic organics, metal ions, and radionuclides.
• Offers high selectivity in separations requiring low water miscibility and strong phase stability.
• Useful in supported ionic liquid membranes (SILMs) for gas separation and organic vapor transport.

5. Materials Processing and Polymer Engineering

• Used as a processing aid and dispersant for nanomaterials, carbonaceous fillers, and metal oxides.
• Enhances dispersion stability in polymer matrices and composite formulations.
• Serves as a plasticizer or rheology modifier in high‑performance polymers.

6. Antistatic, Surface, and Coating Applications

• Provides durable antistatic performance in coatings, films, and engineered surfaces.
• Contributes to hydrophobic, low‑surface‑energy coatings with chemical and thermal resistance.
• Supports surface functionalization of metals, ceramics, and carbon materials.

7. Analytical and Spectroscopic Uses

• Utilized as a stable, low‑volatility matrix or solvent for mass spectrometry and spectroscopic studies.
• Offers controlled microenvironments for studying reaction kinetics and ion–molecule interactions.
