| 摘 要： | 3,3-双(二氟氨甲基)氧杂环丁烷(BDFAO)是一种新型的二氟氨基含能化合物。以3,3-二氯甲基氧杂环丁烷(BCMO)为起始原料,通过胺化、酯化、氟化反应合成出BDFAO,总收率约43%。利用红外光谱、核磁共振、元素分析对合成产物进行了表征,确定其为目标产物。气相色谱分析BDFAO的纯度大于97%。利用TG-DTA对合成的BDFAO的热性能进行了分析,结果表明BD FAO熔点为43.5℃,在15～200℃范围内BDFAO未发生分解,其热稳定性较好。采用GJB772 A-1997中规定的方法对BDFAO的撞击、摩擦感度进行了测试,BD FAO的撞击感度H50为28.5 cm(5 kg落锤),摩擦感度为100%(摆角90°,压力3.92 MPa),表明BDFAO是一种对撞击较为钝感、但对摩擦敏感的含能材料。

| Abstract: | 3,3-Bis(difluoroaminomethyl)oxetane(BDFAO) is a new energetic compound.BDFAO was synthesized from 3,3-bis(chloromethyl)oxetane(BCMO) by amination,esterification and fluorination.Total yield is about 43%.Synthesized compounds were characterized by IR,1H NMR,13C NMR,GC(gas chromatograph) and elemental analysis.It was proved to be BDFAO and its purity is above 97%.The thermal properties of synthesized BDFAO were investigated by TG-DTA(thermogravimetry and differential thermalanalysis).Results show it has better thermal stability and its melting point is about 43.5 ℃.The sensitivities of BDFAO were determined by GJB772A-1997.The impact sensitivity H50 is about 28.5 cm(5 kg hammer),the friction sensitivity is 100%(90° angle,3.92 MPa) and it is insensitive to impact but sensitive to friction. |
