Abstract:

以2-偕二硝甲基-5-硝基四唑(HDNMNT)和醇钠为原料,合成出2-偕二硝甲基-5-甲氧基四唑(DNMMOT)、2-偕二硝甲基-5-乙氧基四唑(DNMEOT)、2-偕二硝甲基-5-异丙氧基四唑(DNMPOT)、2-(2-偕二硝甲基四唑-5-氧基)乙醇(SDEH)以及1, 2-双(2-偕二硝甲基四唑-5-氧基)乙烷(DEH)5种化合物,产率分别为91.6%、92.1%、91.7%、31.7%及57.4%。采用红外光谱、核磁共振、元素分析及液相色谱质谱联用技术等对其结构进行了表征,并推测该反应机理为HDNMNT与醇钠的亲核取代反应。采用B3LYP方法预估了这5种2-偕二硝甲基-5-烷氧基四唑化合物的爆轰性能,发现DEH与RDX爆速和爆压相当
