摘　　要：以间苯二甲腈、双氰胺、乙醇胺为原料,以氢氧化钾、乙酸锌为催化剂,在有机溶剂中通过两步反应合成了一种新型含氮反应型阻燃剂—6-[3-(2-噁唑啉基)苯代]-1,3,5-三嗪环-2,4-二胺,产率达84%。采用红外光谱、核磁共振氢谱对其结构进行了表征,并采用热失重分析测试了其热行为。结果表明,该化合物具有较好的热稳定性,700℃时的残炭率为13.23%。A novel nitrogen-containing reactive flame retardant, 6-[ 3- （2-oxazolyl） phenyl ] -1, 3, 5-triazinc-2, 4-diamine was synthesized using phthalonitrile, dicyandiamide and ethanolamine as raw materials, potassium hydroxide and zinc acetate as catalysts in organic solvent through a two-step reaction with a yield of 84%. The structure and thermal property of the synthesized product was characterized and analyzed by Fourier transform infrared spectroscopy （FT-IR）, ^1H-NMR and thermogravimetic analysis （TGA）. Results showed that the product had good thermal stability ; and had a char yield of 13.23% at 700℃.
