摘要
以 3,4 -二氨基呋咱为起始原料合成无氢含能化合物 3,3′-二硝基氧化偶氮呋咱 (DNOAF) ,利用 IR、NMR、MS和元素分析鉴定了其结构。通过计算得出 ,DNOAF的标准生成焓为 6 4 0 k J/mol,爆速 D=9390 m/s,爆压 PCJ=4 0 .5 GPa。按照以 2 0 % DNOAF取代NEPE推进剂中的 HMX计算 ,复合推进剂的比冲为 2 6 9.2 s-1(以 HNIW取代则为 2 6 8.7s-1)。
dinitroxazafurazan(DNOAF)was synthesized from 3,4 dinaminofurazan as a non hydrogen energetic compound. Its structure has been identified by IR, NMR, MS and elemental analysis .The standard formation enthalpy, detonation velocity and detonation pressure of DNOAF were calculated to be 640 kJ/mol, 9390 m/s and 40.5 GPa respectively. Calculation shows that the specific impulse is 269.2 s -1 of NEPE propellant by substituting 20% of HMX with the title compound (if HNIW was substituted for HMX , the specific impulse is 268.7 s -1 ).
