Abstract:

以4H,8H-双呋咱并[3,4-b:3′,4′-e]吡嗪(DFP)为原料,经成盐、取代、加成、硝化、氯化、叠氮化等反应合成了六种双呋咱并吡嗪衍生物(Ⅰ~Ⅵ);利用红外光谱、核磁共振、元素分析等鉴定了其结构。对氮氧含量较高的含有硝基呋咱、硝酸酯、叠氮官能团衍生物Ⅱ、Ⅳ、Ⅵ采用差示扫描量热(DSC)、热重(TG)考察了其热性能,三者的分解峰温分别为318.3,197.5,250.5℃,热稳定性较好。并用Gaussian09和VLW程序计算了其物化及爆轰性能,Ⅳ的密度为2.00g·cm-3,爆速9067m·s-1,爆压43GPa,其爆速与HMX相近,密度和爆压均大于HMX。
