| Abstract: | Hexakis(2,4,6-tribromophenoxy)cyclotriphosphazene(BPCPZ) was prepared via the reaction of hexachlorocyclotriphosphzene and 2,4,6-tribromophenol.The structure of BPCPZ was characterized by FT-IR,MS,1HNMR,31PNMR,13C NMR spectroscopy and elemental analysis.The factors affecting the yield of BPCPZ,such as reagent,molar ratio of 2,4,6-tribromophenol/hexacholrocyclotriphosphazene,reaction temperature(T) and reaction time(t) were investigated.The optimized process conditions were:n(2,4,6-tribromophenol)/(hexacholrocyclotriphosphazene)=6.56,T=65℃,t=24 h,and tetrahydrofuran as solvent.The yield of BPCPZ was 98%.The compound has perfect heat-resistance and flame retardant resistance and can be used as organic filler in insulation layer for the solid rocket motor. |
