The invention discloses a cyclotriphosphazene derivative containing 4-methoxyphenylethylamino, and particularly relates to an application and preparation method of the derivative, belonging to the technical field of flaming retarding. Hexachlorocyclotriphosphazene and 4-methoxyphenylethylamine are subjected to a nucleophilic substitution reaction under alkaline condition and then filtration, concentration, washing and other steps are performed to obtain hexa(4-methoxyphenylethylamino) cyclotriphosphazene. The method has advantages of mild reaction condition, easy control and good repeatability, and the prepared compound has good flame retarding effects, can achieve good flame retarding effects with a low dosage, is not liable to decompose through heating and can be used as a good flame retardant. 本发明公开一种含4-甲氧基苯乙胺基的环三磷腈衍生物，具体涉及到含4-甲氧基苯乙胺的环三磷腈衍生物的制备方法及应用，属于阻燃技术领域。使六氯环三磷腈和4-甲氧基苯乙胺在碱性条件下发生亲核取代反应，之后过滤、浓缩、洗涤等得到六(4-甲氧基苯乙胺基)环三磷腈。本发明反应条件温和，易于控制，重复性好，并且制得的化合物具有阻燃效果好，阻燃添加量少即可以达到很好的阻燃效果，同时加热不易分解。可作为一种良好的阻燃剂使用。
