Tributylethylphosphonium diethyl phosphate, CAS: 20445-97-7

Key Applications:

Hybrid Additive Systems

• Functions as a co-additive in hybrid lubricant formulations where organophosphate functionality enhances boundary film formation.
• Supports synergistic performance when blended with phosphonium or imidazolium ionic liquids, improving load-bearing capacity and reducing wear.
• Useful in multi-component additive packages for advanced tribological studies, enabling controlled tuning of frictional behavior.

Viscosity Modification and Control

• Acts as a viscosity modifier in lubricant basestocks, offering stable rheological behavior across broad temperature ranges.
• Enhances flow characteristics in ionic liquid–hydrocarbon blends, improving pumpability and low-temperature performance.
• Supports formulation of shear-stable fluids for high-stress mechanical environments.

Thermal and Oxidative Stability Enhancement

• Contributes to improved thermal stability in high-temperature lubricant systems due to the inherent robustness of phosphonium cations.
• Serves as a stabilizing component in fluids exposed to oxidative stress, extending operational lifetimes.

Catalysis and Reaction Media

• Provides a polar, thermally stable medium for catalytic transformations requiring controlled acidity or organophosphate coordination.
• Suitable for use in biphasic or semi-homogeneous systems where selective solvation and phase behavior are critical.

Materials Processing and Surface Engineering

• Supports surface modification studies where ionic liquid–phosphate interactions influence film deposition or interfacial behavior.
• Useful in polymer processing environments requiring antistatic behavior, controlled viscosity, or enhanced thermal resistance.
