摘要
分别用三氯化磷法和三氯氧磷法合成了数种标题化合物。用ＩＲ光谱和ＮＭＲ光谱对产物的结构进行了分析，与预期相符。使用标题物配制成添加型复合阻燃剂，对环氧树脂Ｅ－４４进行了阻燃处理。氧指数测试结果表明：标题物含磷量高，阻燃效果好；溴、磷等元素的协同作用，使其阻燃效果更佳。
Twelve title compounds were synthesized using phosphorous trichloride and phosphorus oxychloride as chlorinating agents respectively.The properties of the title compounds used as flame retardancies were also investigated.The results of experiments show that the higher the content of phosphorous in the compounds,the better the effect of retardancy.
