General description
Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate is a phosphonium-based ionic liquid. It can be prepared by reacting trihexyl(tetradecyl)-phosphonium chloride with bis(2,4,4-trimethylpentyl)phosphinic acid in the presence of a base.

Application
It can be used as an extractant for the removal of dibenzothiophene from liquid fuels via extractive desulfurization (EDS).
Features and Benefits
Phosphonium-based ionic liquid possess interesting properties such as:
- Liquid at room temperature or melting at T <100 °C
- High thermal stability
- Immiscible with water
- Soluble in organic solvents (however, when an excess of water is added to the system, three liquid phases are formed)
- Stable under basic conditions
Other Notes
A phosphonium phosphinate for use as a polar solvent
