Trihexyltetradecylphosphonium bis(2,4,4-Trimethylpentyl)phosphinate, CAS: 465527-58-6

Key Applications:

Solvent Extraction & Hydrometallurgy

• Serves as a highly selective extractant for metal ions in non‑aqueous and biphasic systems.
• Supports separation of rare earths, actinides, and transition metals through strong ion‑pairing and tunable hydrophobicity.
• Enables low‑emulsion, rapid phase disengagement in continuous extraction equipment.

Phase‑Transfer & Interfacial Catalysis

• Functions as a hydrophobic phase‑transfer agent for reactions involving poorly soluble substrates.
• Enhances reaction rates in alkylation, substitution, and condensation processes by stabilizing reactive intermediates at the organic–aqueous interface.
• Suitable for high‑temperature catalytic environments due to excellent thermal stability.

Non‑Aqueous Electrochemistry

• Provides a stable, low‑volatility medium for electrochemical studies in hydrophobic solvents.
• Supports wide electrochemical windows and stable ion mobility in battery, capacitor, and corrosion‑inhibition research.
• Useful as an electrolyte additive to improve interfacial behavior in metal deposition systems.

Lubrication & Surface Modification

• Acts as a boundary‑layer lubricant in high‑pressure, high‑temperature environments.
• Forms durable, low‑friction films on metals and alloys due to strong surface adsorption of the phosphonium cation.
• Used in anti‑wear, anti‑seize, and extreme‑pressure lubricant formulations.

Polymer Processing & Additive Systems

• Serves as a compatibilizer or plasticization aid in hydrophobic polymer matrices.
• Enhances dispersion of fillers and pigments in non‑polar systems.
• Useful in tailoring mechanical and thermal properties of specialty elastomers and engineering plastics.

Antistatic & Anti‑Dusting Agents

• Provides long‑lasting charge dissipation in hydrophobic coatings and polymer surfaces.
• Effective in low‑humidity environments where conventional antistatic agents fail.

Separation Science & Chromatography

• Employed as a stationary‑phase modifier in liquid–liquid chromatography and supported liquid membranes.
• Offers strong retention of hydrophobic analytes and tunable selectivity.
