Abstract:

The effects of static pressures in the kbar range on the thermal decomposition of 2,2-DNP have been studied. O2 and NO2 play no important role in the autocatalytic decomposition of 2,2-DNP, but the application of pressure to these systems at appropriate temperature bring about exothermic chain decomposition. Thermal decomposition of both 1,1- and 2,2-DNP were followed visually at autogenous pressures in small tubes. NO2 was formed initially in large quantities, and then after a still period, the sample tubes burst violently. The authors suggest that NO2 is an important initial product in confined samples at adequately high temperatures and pressures, and further propose that NO3 generated in the equilibrium 2NO2 O2NONO NO3 NO is the important energetic species evolved at high pressures leading to detonation initiation.
