Trihexyltetradecylphosphonium bis(nonafluorobutanesulfonyl)imide, CAS: 1256247-32-1

Key Applications:

1. High‑Temperature and High‑Shear Lubrication

• Functions as a non‑volatile, thermally stable lubricant or lubricant additive for extreme‑environment mechanical systems.
• Provides low wear and friction under elevated temperatures due to strong cation–anion stability and minimal oxidative degradation.
• Useful in aerospace, vacuum systems, and sealed industrial gear assemblies where conventional lubricants fail.

2. Hydrophobic Extraction and Phase‑Transfer Media

• Serves as a selective extraction phase for hydrophobic organics, fluorinated compounds, and metal–organic species.
• Enables biphasic catalysis and phase‑transfer processes where water immiscibility and chemical inertness are required.
• Suitable for solvent replacement strategies in green chemistry workflows.

3. Electrochemical and Energy‑Storage Systems

• Acts as a stable ionic medium for high‑voltage or high‑temperature electrochemical devices.
• Supports wide electrochemical windows and low flammability, making it relevant for specialized capacitors, redox systems, and ionic‑liquid‑based electrolytes.
• Useful in research on fluorinated anion electrolytes for next‑generation energy materials.

4. Surface Modification and Anti‑Fouling Coatings

• Forms durable, hydrophobic surface layers on metals, ceramics, and polymers.
• Reduces surface energy and enhances resistance to fouling, corrosion, and moisture uptake.
• Applicable in marine coatings, industrial equipment protection, and anti‑adhesion treatments.

5. Thermal‑Management Fluids

• Suitable for heat‑transfer applications requiring low volatility, chemical inertness, and stability at elevated temperatures.
• Can be used in closed‑loop thermal systems, specialty reactors, and high‑temperature process equipment.

6. Catalyst Stabilization and Non‑Coordinating Reaction Media

• Provides a non‑coordinating, chemically inert environment for sensitive catalysts, including organometallic and Lewis‑acid systems.
• Enhances catalyst lifetime and selectivity in transformations that benefit from low nucleophilicity and high hydrophobicity.

7. Fluorinated‑Anion Research and Materials Development

• Useful as a model system for studying structure–property relationships in fluorinated ionic liquids.
• Supports development of advanced materials where low viscosity, hydrophobicity, and thermal resilience are required.
