Evidence is presented to support the observation by electron paramagnetic resonance (EPR) of nitroxide radicals formed by intermolecular coupling during the thermal decomposition of 2,4,6-trinitrotoluene (TNT) alone and during thermolysis of TNT in the presence of hexamethylbenzene (HMB) or perdeuteriohexamethylbenzene (HMB-d/sub 18/). Similar results are reported for the thermal reaction of 1,3,5-trinitrobenzene (TNB) with HMB, HMB-d/sub 18/, and TNT. A reaction mechanism is proposed. An unidentified nitroxide radical has been separated chromatographically from TNT thermolysis products. 14 references, 2 figures, 1 table.
