| Abstract: | The synthesis of(ethoxy)pentafluorocyclotriphosphazene was studied as a flame retardant in electrolytes for lithium ion batteries. With hexachlorocyclotriphosphazene as raw material, sodium fluoride as fluorinated agent, DMI(1,3-dimethylimidazolidin-2-one) as a solvent for fluorination reaction, distilled to obtain hexafluorocyclotriphosphazene(P3N3F6>98%). With hexafluorocyclotriphosphazene as raw material, n-hexane as solvent, sodium ethoxide as ether reagent, react to obtain crude products, crude product was distilled to obtain(ethoxy)-pentafluorocyclotriphosphazene with purity of 99.8%. |
