摘要
合成了一种新的高分子模型化合物———六(4-乙氧羰苯氧基)三聚磷腈,用红外光谱、核磁共振氢谱、碳谱和质谱证实了该中间体的结构,用正交试验优化了该中间体的合成方法.结果表明,合成六(4-乙氧羰苯氧基)三聚磷腈的较好方法为:以2.4 g K2CO3为催化剂,用1 g六氯三聚磷腈与3.5 g对羟基苯甲酸乙酯在丙酮中回流8 h,产率为93.9%.
Hexakis (4-carboxylic acid ethyl ester phenoxy) cyclotriphosphazenes, a new model compound for phosphazene high polymers was synthesized. Its structure was characterized by IR, ^1 HNMR, ^13 CNMR, 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 hexachlorocyclotriphosphazene(1g) with ethyl 4-hydroxybnzoate (3.5g) in the presence of K2CO3(2.4g) as a catalyst and acetone as a solvent at refluxing temperature for & 8 h. The yield of the product was 93.9% .
