Trihexyltetradecylphosphonium hexafluorophosphate, CAS: 374683-44-0

Key Applications:

Liquid–liquid extraction and phase‑transfer systems

• Serves as a hydrophobic extraction medium for metal ions, lanthanides, actinides, and organometallic complexes.
• Enhances selectivity in biphasic separations due to its low miscibility with water and strong affinity for neutral or weakly polar solutes.
• Used as a phase‑transfer agent for reactions involving poorly soluble substrates.

Catalysis and reaction media

• Provides a non‑volatile, thermally stable solvent for high‑temperature organic transformations.
• Supports acid‑catalyzed, base‑catalyzed, and transition‑metal‑catalyzed reactions by stabilizing reactive intermediates.
• Employed in biphasic catalytic systems where product separation and catalyst recycling are essential.

Electrochemical and energy‑related applications

• Functions as a hydrophobic ionic liquid electrolyte with wide electrochemical stability windows.
• Used in electrodeposition, corrosion‑resistant coatings, and high‑temperature electrochemical cells.
• Serves as a component in ionic‑liquid‑based electrolytes for supercapacitors and advanced battery research.

Materials processing and polymer modification

• Acts as a plasticizer, dispersant, or processing aid for hydrophobic polymers and elastomers.
• Facilitates nanoparticle stabilization and surface functionalization in nonpolar media.
• Supports templating and structuring processes in advanced materials synthesis.

Lubrication and tribology

• Provides boundary lubrication in high‑temperature or vacuum environments due to its low volatility and strong surface affinity.
• Used in ionic‑liquid‑enhanced greases and specialty lubricants for demanding mechanical systems.

Environmental and analytical chemistry

• Serves as a solvent or extraction phase in sample preparation, including SPE and SPME.
• Enables preconcentration of hydrophobic analytes for chromatographic and spectroscopic analysis.
