Synthesis and Characterization of Tri-phenoxy-tri-(4-nitrophenoxy)-cyclotriphosphazene

Tri-phenoxy-tri-(4-nitrophenoxy)-cyclotriphosphazene was synthesized by using sodium phenolate,sodium 4-nitrophenolate and hexachlorocyclotriphosphazene as raw materials.The product was characterized by FT-IR,1H-NMR,LC-MS,13C-NMR and 31P-NMR.HCCTP,sodium phenolate and sodium 4-nitrophenolate taken in the molar ratio of 1∶3∶3.5 were dissolved in tetrahydrofuran(THF),reacting at 65 ℃ for 7 h and the product was gained.
