Trihexyltetradecylphosphonium chloride, CAS: 258864-54-9

Key Applications:

1. Phase‑Transfer and Multiphase Catalysis

• Enhances reaction rates in systems involving immiscible phases.
• Facilitates transport of reactive species into organic media.
• Useful in alkylation, substitution, and condensation reactions requiring robust, non‑volatile transfer agents.

2. Electrochemical Systems and Energy Materials

• Serves as a hydrophobic ionic liquid component in electrolytes for batteries, supercapacitors, and electrodeposition processes.
• Supports wide electrochemical windows and stable ion transport in non‑aqueous environments.
• Useful in research on ionic‑liquid‑based electrolytes for high‑temperature or high‑stability applications.

3. Extraction, Separation, and Solvent Systems

• Acts as a tunable solvent or co‑solvent for metal ion extraction, hydrophobic solute dissolution, and biphasic separations.
• Suitable for liquid–liquid extraction of transition metals and organics.
• Provides low volatility and strong thermal resistance for closed‑loop separation processes.

4. Materials Processing and Surface Modification

• Functions as a structure‑directing agent or processing aid in polymer, nanoparticle, and composite fabrication.
• Supports dispersion and stabilization of hydrophobic fillers or additives.
• Can be incorporated into ionic‑liquid‑modified surfaces for improved lubrication or anti‑fouling behavior.

5. Organic Synthesis and Specialty Chemical Manufacturing

• Provides a stable, reusable ionic medium for reactions requiring high temperatures or low vapor pressure.
• Enhances solubility of hydrophobic substrates and intermediates.
• Useful in green‑chemistry workflows seeking to replace volatile organic solvents.
