Trihexyltetradecylphosphonium bis(2-ethylhexyl)phosphate, CAS: 1092655-30-5

Key Applications:

Hydrometallurgical and Solvent Extraction Systems

• Functions as a high‑efficiency extractant for rare‑earth and transition‑metal ions due to the coordinating, acidic bis(2‑ethylhexyl)phosphate (DEHP) anion.
• Enables phase‑transfer extraction in biphasic ionic liquid/organic or ionic liquid/aqueous systems, improving selectivity for Fe³⁺, Co²⁺, Ni²⁺, and lanthanides.
• Supports low‑volatility, reusable extraction media that reduce solvent loss and improve process sustainability.

Antiwear and Boundary Lubrication Additive

• The phosphate anion provides robust antiwear and extreme‑pressure performance through formation of protective tribofilms on metal surfaces.
• The long‑chain phosphonium cation enhances thermal stability and surface affinity, supporting high‑load, high‑temperature lubrication environments.
• Suitable for synthetic esters, PAOs, and ionic‑liquid‑based lubricant blends used in aerospace, industrial, and automotive systems.

Thermally Stable Ionic Liquid Matrix

• Exhibits excellent thermal and oxidative stability, enabling use as a base ionic liquid or co‑solvent in high‑temperature processes.
• Supports ion‑conductive environments for electrochemical devices where phosphate coordination improves interfacial behavior.

Surfactant and Interfacial Modifier

• Amphiphilic structure provides strong interfacial activity, enabling emulsification, dispersion, and stabilization of nanoparticles or hydrophobic actives.
• Useful in nanomaterial processing, pigment dispersion, and formulation of non‑aqueous emulsions.

Plasticizer‑Compatible Processing Aid

• The bis(2‑ethylhexyl)phosphate anion is structurally similar to common plasticizers, enabling compatibility with PVC, elastomers, and flexible polymer systems.
• Enhances processability, flexibility, and thermal stability in specialty polymer formulations.

Antistatic and Surface‑Modification Agent

• Provides durable antistatic performance in coatings, films, and polymer surfaces due to its persistent ionic character.
• Applicable in electronics packaging, cleanroom materials, and dust‑repellent coatings.
