Abstract
Exothermic reactions of some self igniting fuel‐HNO~3~ systems have been examined by the rapid‐scan FIR/thermal profiling technique. A sudden rise in temperature is observed when the liquid oxidizer is dropped onto the solid fuel. Simultaneous monitoring of the gas products of the reaction occurring between p‐phenylenediamine and HNO~3~ reveals the formation of Co~2~, NO~2~ and HONO. Immediate evolution of NO~2~ is observed in the synergistically igniting systems comprised of substituted anilines, Mg and HNO~3~. Thiocarbohydrazide and its acetone and benzaldehyde monoderivatives on reacting with HNO~3~ produce SO~2~, NO~2~ and, possibly, OCS. The results are explained in terms of the oxidation and nitration reactions occurring in these systems.
