Abstract
The standard enthalpies of formation of 1,1-bis(methoxy-NNO-azoxy)-3-nitro-3-azabutane and 1,1,8,8-tetrakis (methoxy-NNO-azoxy)-3,6-dinitro-3,6-diazaoctane were experimentally determined to be 87.7 \(\pm\) 3.9 and 283.8 \(\pm\) 6.2 kJ/mol, respectively. Calculations have shown that solid composite propellants containing these two compounds as gasifying components in metal-free compositions based on an active binder and ammonium perchlorate are inferior in the maximum achievable effective impulse at the third stage of the rocket system \(I_{ef}\)(3) to compositions based on HMX, but in designing special compositions with a limited content of organic explosive (not higher than 30–35%), these two compounds provide 5–10 s higher values of \(I_{ef}\)(3) than when using HMX.
