HEXAFLUOROCYCLOTRIPHOSPHAZENE

The Uses of HEXAFLUOROCYCLOTRIPHOSPHAZENE

Hexafluorocyclotriphosphazene is an intermediate for organic materials, which can be used as a raw material for the synthesis of other components or electronic materials, and can be used in the preparation of spiro ethers and flame retardant additives for lithium ion batteries.

Synthesis

Hexafluorocyclotriphosphazene is prepared by the reaction of potassium fluoride and 2,2,4,4,6,6-hexachloro-1,3,5-triaza-2,4,6-triphosphorine. The steps are as follows:
Put 104.3g of hexachlorocyclotriphosphazene, 113.3g of potassium fluoride, 0.011g of ionic liquid catalyst [Nbmm]OH, and 217.6g of anhydrous acetonitrile in an electric stirrer, thermometer, In the flask with reflux condenser, the reaction was carried out at 30°C, and the reaction was closed after 2h, filtered, The filtrate was rectified to obtain hexafluorocyclotriphosphazene with a yield of 98.7%.
