Studies on the synthesis of hexakis(4- carboxylic acid ethyl ester phenoxy) cyclotriphosphazenes

Hexakis(4-carboxylic acid ethyl ester phenoxy)cyclotriphosphazenes,a new model compound for phosphazene high polymers was synthesized.Its structure was characterized by IR,¹HNMR,¹CNMR,DEPT and FABMS.The synthetic method was optimized with orthogonal test.The results indicated that the appropriate synthetic method was a follows: the title compound was prepared by reaction of hexachlorocy-clotriphosphazene(1 g)with ethyl 4-hydroxybenzoate(3.5 g)in the presence of K₂CO₃(2.4 g)as a catalyst and acetone as a solvent at refluxing temperature for &; 8 h.The yield of the product was 93.9%.
