| | Dibenzo-24-crown-8 Usage And Synthesis |
| Chemical Properties | white powder | | Uses | Dibenzo-24-crown-8 can be used as a molecular transporter in the formation of [1]rotaxanes with thiazolium-based mono- and tris-branched ammonium ions. It is also used as a co-solvent and phase-transfer catalyst for cesium fluoride, to the development of a more efficient anhydrous fluorinating system for organic synthesis. | | Purification Methods | Recrystallise it from EtOH, and dry in a vacuum at 60o over P2O5 for 16hours.
