Trihexyltetradecylphosphonium dicyanamide, CAS: 701921-71-3

Key Application:

• Advanced Lubrication & Tribology: 

Utilized as a high‑performance boundary lubricant and friction‑reducing additive in synthetic oils. Its long‑chain phosphonium cation forms durable interfacial films suitable for high‑load, high‑temperature tribosystems.

• Electrochemical Systems & Energy Storage: 

Serves as a thermally stable, non‑volatile ionic medium for electrochemical devices requiring wide electrochemical windows. Applied as a supporting electrolyte in redox systems, capacitors, and emerging battery chemistries.

• Reaction Media & Catalysis: 

Provides a hydrophobic, non‑coordinating environment for organometallic, base‑sensitive, and biphasic catalytic transformations. Enhances substrate solubilization in phase‑transfer catalysis and supports transition‑metal catalysis.

• Surfactants, Coatings & Materials Processing: 

Functions as a surface‑active ionic liquid for modifying polymer, metal, and nanoparticle interfaces. Used in anti‑static and hydrophobic coatings and to improve nanoparticle dispersion in nonpolar matrices.

• High‑Temperature & Harsh‑Environment Applications: 

Suitable for thermal management fluids and heat‑transfer media where conventional organics degrade. Performs reliably in vacuum, high‑temperature, and chemically aggressive environments due to the stability of the phosphonium framework.
