-1 K -1 ), entalpia de ativacao (ΔH ≠ , sal 1, 278,7 kJ mol -1 ; sal 2, 113,1 kJ mol -1 ), energia livre de ativacao (ΔG ≠ , sal 1, 117,6 kJ mol -1 ; sal 2, 110,9 kJ mol -1 ), calor de formacao (ΔHf 0 , sal 1, 264,7 kJ mol -1 ; sal 2, 487,6 kJ mol -1 ), temperatura critica de explosao termica (Tb, sal 1, 412,3 K; sal 2, 388,9 K) implicam que os sais sintetizados sao seguros o suficiente durante o estoque ou uso; em vista da pressao de detonacao (P, sal 1, 30,2 GPa; sal 2, 29,1 GPa) e da velocidade de detonacao (D, sal 1, 8398 m s -1 ; sal 2, 8334 m s -1 ), acredita-se que os dois sais baseados em 1-amino-2-nitroguanidina possuem potencial para serem usados como materiais energeticos. Two nitrogen-rich energetic materials based on 1-amino-2-nitroguanidine were synthesized. The thermal behavior, thermodynamic properties, electron structures and detonation properties were investigated. The dynamic (DSC) curves show that 1-amino-2-nitroguanidinium 2,4,5-trinitroimidazole (salt 1) can be used as cast explosives. These curves allow determination of their melting points and thermodynamic parameters such as activation energy (Ek, salt 1, 282.1 kJ mol -1 ; salt 2, 116.2 kJ mol -1 ; Eo, salt 1, 275.0 kJ mol -1 ; salt 2, 116.9 kJ mol -1 ),
