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
