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 ± 3.9 and 283.8 ± 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 highest achievable effective impulse at the third stage of the rocket system Ief(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 Ief (3) than when using HMX.
