三（2，4，6－三溴苯氧基）锑的合成与阻燃性能研究

STUDIES ON THE SYNTHESIS OF TRIS-(2,4,6-TRIBROMOPHENOLATO)ANTIMONY(Ⅲ)AND IT'SFLAME RETARDING CHARACTER

本文研究了三（２，４，６－三滇苯氧基）锑的合成方法及其阻燃性能．用苯酚、溴和三氯化锑在一定条件下可合成该化合物，产率达８６％以上；该化合物在３４０℃以下是稳定的，对聚乙烯和聚丙烯都具有良好的阻燃效果，当其在聚乙烯和聚丙烯中的添加量分别为５％和８％时，氧指数就提高到了２６．８和２８．３，且对阻燃产品的其它性能无不良影响．

In this paper, a method of synthesizing tris-(2,4, 6-tribromophenolato) antimony(Ⅲ) was reported,and the flame retarding character of this compound was also approached. The compound was propared by the reaction of tribromophenol with antimonous chloride in proper conditions,the yield reached 86. 5%. In polyethylene (PE) and polypropylene(PP),the compound has a high efficiency of flame retarding.
