自行设计并合成了一种含有氟偕二硝基的新型高能增塑剂3,4-二(3-氟偕二硝基-4-氧)呋咱。通过FT-IR、~(13)C NMR、~(19)F NMR、元素分析、DSC等分析手段进行了结构表征。基于计算的标准生成焓以及实测的密度,采用Kamlet-Jacobs方程计算了3,4-二(3-氟偕二硝基-4-氧)呋咱的爆轰性能,并与常用增塑剂:硝化甘油(NG)和二(氟偕二硝基)甲醛(FEFO)和3,3′-二硝基双呋咱醚(FOF-1)的爆轰性能进行了对比。结果表明,3,4-二(氟偕二硝基-4-氧)呋咱具有热稳性好(分解温度197.8℃)、密度大(1.88g·cm~(-3))、熔点低(50℃)和能量水平高等特点,是一种综合性能优异的含能增塑剂。
A novel high-energy plasticizer 3,4-bis (3-fluoronitro-dinitro-4-oxyl) furazan was designed and synthesized. The structures were characterized by FT-IR, ~ (13) C NMR, ~ (19) F NMR, elemental analysis and DSC. Based on the calculated standard enthalpy of formation and the measured density, the detonation performance of 3,4-bis (3-fluoro gem dinitro-4-oxo) furazan was calculated by the Kamlet-Jacobs equation and compared with the common plasticizer: The detonation performance of nitroglycerin (NG) with bis (fluorfenamidothio) formaldehyde (FEFO) and 3,3’-dinitrobifurazan (FOF-1) was compared. The results showed that 3,4-bis (fluorodeoxy-dinitro-4-oxo) furazan has good thermal stability (decomposition temperature 197.8 ℃), high density (1.88g · cm -3) 50 ℃) and high energy level, is a comprehensive performance of the plasticizer containing energy.
