Preparation and properties of 3-amino-5-nitro-1,2,4-triazole
A novel method for the preparation of 3-amino-5-nitro-1,2,4-triazole (ANTA) has been invented. The yield of ANTA by selective reduction of the ammonium salt of 3,5-dinitro-1,2,4-triazole with hydrazine hydrate is 94% to 96% under mild reaction conditions. There is no volatile hydrazine present at the end of the reaction as it is isolated as hydrazine hydrochloride. ANTA, a potential insensitive explosive, has a crystal density of 1.82 g/cm{sup 3}, and a positive heat of formation ({Delta}H{sub f}) of 21.0 kcal/mol, and is thermally stable. The detonation velocity of ANTA, calculated at crystal density, is higher than that of triaminotrinitrobenzene. In addition to the preparation of ANTA, we have also synthesized a new hydrazinium salt of ANTA. 6 refs., 2 tabs.
