摘要: 磷腈化合物是一类无卤、对环境友好且具有生物相容性的低毒性阻燃剂,但大部分磷腈衍生物是油溶性的,需要通过熔融共混、辊轧等方式才能制成阻燃纤维、塑料,操作工艺复杂,无法直接用于天然纤维,因此大大限制了其应用范围.该文以六羟甲基三聚氰胺和六氯环三磷腈为原料,通过亲核取代、醚化两步法合成了一种水溶性、醇溶性无卤磷腈阻燃剂.用红外光谱(FTIR)、核磁共振谱(^1H NMR、^13C NMR、^31P NMR)和电喷雾电离质谱(ESI-MS)等进行了结构表征,证明其为无氯、P螺原子链接的目标化合物.将该阻燃剂用Abstract: The phosphazenebased compounds are halogenfree and environmentallyfriendly. Some of them are biocompatible and can be used as flame resistant materials. However, these compounds often lack watersoluble. Some reports attempted to produce a fireretar
