Description 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. http://www.sigmaaldrich.com/dam/sigma-aldrich/docs/Aldrich/Acta/al_acta_37_1.pdf Application It can be used as an extractant for the removal of dibenzothiophene from liquid fuels via extractive desulfurization (EDS). Packaging 5, 50 g in poly bottle 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
