Abstract:

Cyclic nitramines such as HMX and RDX are energetic materials used in propellants and explosives. One of the keys to understanding the ignition and combustion of these compounds is a characterization of the pathways involved in their unimolecular decomposition. This information is difficult to obtain since the utility of energetic materials is based on their propensity to undergo extremely rapid, exothermic reactions. Moreover, functionally useful nitramines may decompose via a number of possible pathways, and secondary bimolecular reactions involving product radicals may obscure the identity of the initial reaction products. Because of these difficulties, dimethylnitramine DMNA, CH32NNO2, has been studied as a simple analog expected to exhibit some of the processes important in cyclic nitramine decomposition. DMNA decomposition has been investigated in thermal pyrolysis.
