Application

Reactant for:
  • Preparation of ionic liquids via solvent-free anion metathesis reaction
  • Preparation of tetraalkylphosphonium tungstophosphate and isopolytungstate Lindquist cluster anion
Trihexyltetradecylphosphonium bromide is a phosphonium-based ionic liquid that can be used as a recyclable reaction medium for Heck cross-coupling reactions. It can also be used to prepare supported liquid membranes (SLMs) for gas separation processes.

A new approach has been developed to improve SO2 sorption by cyano-containing ionic liquids (ILs) through tuning the basicity of ILs and cyano-sulfur interaction. Several kinds of cyano-containing ILs with different basicity were designed, prepared, and used for SO2 capture.
