Application

Tetrahexylammonium hydroxide is a phase-transfer reagent that can be used:
  • To synthesize β-D-xyloside- and β-D-xylobioside-based ionic liquids containing tetrahexylammonium cation.
  • As an alkali-free gelling agent to prepare amorphous microporous silica-alumina.
  • To synthesize tetrahexylammonium prolinate, a promising candidate to prepare a solid supported ionic liquid phase (SILP) carbon dioxide absorber.
