The inter- versus intramolecular origin of the products formed in the thermal decomposition of 1,3,5-trinitrohexahydro-s-triazine (RDX) has been traced by isotopic crossover experiments using mixtures of differently labeled analogues of RDX. The isotopic analogues of RDX used in the experiments include 2H, 13C, 15N, and 180. The fraction of isotopic scrambling and the extent of the deuterium kinetic isotope effect (DKIE) are reported for the different thermal decomposition products. Isotopic ...
Through the use of simultaneous thermogravimetry modulated beam mass spectrometry (STMBMS) measurements, time-of-flight (TOF) velocity-spectra analysis, and 2H, 13C, 15N, and 18O labeled analogues of 1,3,5- trinitrohexahydro-s-triazine (RDX), the thermal decomposition products of RDX have been identified as H2O, HCN, CO, CH2O, NO, N2O, NH2CHO, NO2, HONO, (CH3) NHCHO, oxy-s-triazine (OST), and 1nitroso-3,5-dinitrohexahydro-s-triazine (ONDNTA) and all of their gas formation rates have been measured as a function of time. From ...
The products formed in the thermal decomposition of octahydro-1,3,5, 7-tetranitro-1,3,5,7-tetrazocine (HMX) have been traced to using mixtures of different isotopically labeled analogues of HMX. The isotopic analogues of HMX used in the experiments include 2H, 13C, 15NO2, 15N sub ring, and 180. The fraction of isotopic scrambling and the extent of the deuterium kinetic isotope effect (DKIE) are reported for the different thermal decomposition products. Isotopic scrambling is not observed ...
