Characteristics of melt cast compositions based on cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX)/TNT

Popis výsledku v původním jazyce

cis-1,3,4,6-Tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) is has been prepared using a two-stage synthetic method. A new melt cast composition BCHMX/TNT (60/40 by wt.) was prepared. For comparison purposes, Composition B based on RDX /TNT (60/40 bywt.), and HMX/TNT (60/40 by wt.) were also studied. Impact and friction sensitivities of these compositions and of the individual explosives were determined. The detonation velocities were measured experimentally. Their performance was studied by measuring the brisance using the Kast method. The detonation parameters of all explosives were calculated using the EXPLO5 code. Mixing these nitramines with TNT decreases their sensitivities. BCHMX/TNT is more sensitive to impact and friction than CompositionB while it has higher detonation parameters, at the same level as HMX/TNT. BCHMX/TNT has the highest relative brisance of the compositions studied which is due to a higher positive heat of formation for BCHMX.
