Application

It can be used as an extractant for the removal of dibenzothiophene from liquid fuels via extractive desulfurization (EDS).

Caractéristiques et avantages

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

Autres remarques

A phosphonium phosphinate for use as a polar solvent
