Route of Synthesis (ROS)
| Conditions | Yield |
| With n-butylammonium methanoate; sodium fluoride In hexane at 150℃; for 20h; Reagent/catalyst; Solvent; Temperature; Experimental Procedure Dissolve 27.5 g of crystals of ethoxypentachlorocyclotriphosphazene in 200 ml of n-hexane to form an ethoxy pentachloro-cyclophosphazene solution, and add 27 g of sodium fluoride as a fluorinating agent to the solution.2g of butylamine formate was added as a catalyst and reacted at 150°C for 20h.After filtration and distillation under reduced pressure, the phosphazene derivative ethoxypentafluorocyclotriphosphazene was obtained in a yield of 99.6percent. | 99.6% |
| With sodium fluoride In acetonitrile at 80℃; for 5h; Experimental Procedure To the above obtained ethoxypentachloro cyclotriphosphazene in 200g of acetonitrile, 210g NaF was added at constant stirring at a temperature of 80 ° C. The fluorination reaction lasted for 5 hours. The reaction was distilled to give ethoxypentafluoro cyclotriphosphazene (PNF2) 3. | |
| With sodium fluoride; 1-methyl-3-(prop-2-enyl)-1H-imidazol-3-ium tetrafluoroborate at 130℃; for 12h; Reagent/catalyst; Temperature; Experimental Procedure Take 0.1 mole ethoxy pentachloride cyclotriphosphazene and add it into a flask with 100 ml 1-allyl-3-methylimidazolium tetrafluoroborate ionic liquid and then add 1 mole sodium fluoride. Fluoridate 12 hours at 130° C. and then distill at 160° C. to get high-purity pentafluoro ethoxy cyclotriphosphazene. |
