Abstract:
Rates of thermal decompositions for 2,2,4,4,6,6- hexanitroazobenzene HNAB and 2,2,4,4,6,6-hexanitrobiphenyl HNB were measured in the temperature range 215 deg C to 280 deg C by analysis for undecomposed explosive. HNAB decomposed 1.3 hour at 230 deg C, about 18 times faster than HNB. At 280 deg C HNAB decomposed 60hour, 4 times faster than HNB. Supercooled liquids of both HNAB and HNB decomposed faster than the solids measured at the same temperature however, the relative increase in liquid decomposition was much greater for HNB. Isolation and identification of several products from these decompositions indicate the presence of free radicals. Evidence for the formation of picryl radicals during HNAB decomposition is presented.
