Thermodynamic properties, decomposition kinetics and reaction models of BCHMX and its Formex bonded explosive
Original language description
A new energetic material, cis-1,3,4,6-tetranitro-octahydroimidazo-[4,5-d]imidazole (BCHMX) and its plastic explosive (PBX) with styrene-butadiene rubber (SBR) binder (Formex type) have been investigated with regard to its thermal decomposition kinetics and reaction models by using DSC, TG and SEM techniques. It was found that the decomposition of BCHMX in dynamic nitrogen could be divided into two steps, while there is only one step for its Formex bonded explosive. The activation energy for decomposition of BCHMX/Formex was obtained to be 221.7 +- 4.99 kJ mol?1 by modified KAS method, while the mean activation energies for pure BCHMX are calculated as 233.0 +- 2.1 kJ mol?1 for first step and 186.0 +- 0.92 kJ mol?1 for the second step. It was further proved that the first decomposition step of BCHMX is autocatalytic, during which the crystal of BCHMX could dissolve in the liquid phase of its thermolysis products on the surface.
