L-172 Rev Insensitive Explosive Materials: III - 2,3' - Diamino-4,4' - Azoxyfurazan - DAAF
July 2011
Dr Ernst-Christian Koch (Energetic Materials) This report summarizes theoretical and experimental data on the insensitive explosive 3,3’-diamino-4,4’-azoxyfurazan, DAAF, C4H4N8O3.
The title compound offers moderate density, rho = 1.747 g cm-3, and high thermal stability (DSC-onset = 249°C) and is more powerful than similar dense HNS. It derives most of his energy from the high positive enthalpy of formation (444 kJ mol-1) that compensates for its average density. It has a calculated detonation velocity at TMD of 8240 ms-1 and a detonation pressure of 29.35 GPa. The detonation temperature is 3967 K. So far DAAF is mainly explored as insensitive booster explosive. 25 references gathered from the public domain are given.
