THERMAL-DECOMPOSITION OF ENERGETIC MATERIALS .65. CONVERSION OF INSENSITIVE EXPLOSIVES (NTO, ANTA) AND RELATED-COMPOUNDS TO POLYMERIC MELON-LIKE CYCLIC AZINE BURN-RATE SUPPRESSANTS

Selected triazole, tetrazole, triazine, tetrazine, furazan, and acyclic backbone compounds are shown by IR spectroscopy to convert to polymeric, melon-like, cyclic azine residues upon heating to T greater-than-or-equal-to 500-degrees-C. These compounds include the insensitive explosives 3-nitro-1,2,4-triazol-5-one (NTO), 3-amino-5-nitro-1,2,4-triazole (ANTA), and nitroguanidine. The melon-like residue could suppress the burn rate if these compounds are formulated into solid rocket propellants. The IR-active gaseous products from thermolysis are determined as a function of pressure and are related to the atom connectivity in the parent molecules.
