Application

Trihexyltetradecylphosphonium dicyanamide is an ionic liquid that can be used:
  • As an extraction solvent for the separation of organic compounds.[1]
  • In the experiment to study the solubility of carbon dioxide[2] and binary gas mixtures in ionic liquids.[3]
  • To prepare hybrid ionogels having electrochemical applications.[4]
  • As a solvent for the extraction of aromatics from pyrolytic sugars.[5]

Fermentative bioethanol production from pyrolytic sugars was improved via aromatics removal by liquid-liquid extraction. As solvents, the ionic liquid (IL) trihexyltetradecylphosphonium dicyanamide (P666,14[N(CN)2]) and ethyl acetate (EA) were compared. Two pyrolytic sugar solutions were created from acid-leached and untreated pinewood
