Abstract
The standard enthalpies of formation were experimentally measured for four compounds: 4,6-diazido-N-(2,2,2-trinitroethyl)-1,3,5-triazine-2-amine, 6-azido-N2, N4-bis(2,2,2-trinitroethyl)-1,3,5-triazine-2,4-diamine, 6-azido-N2, N4-dinitro-N2,N4-bis(2,2,2- trinitroethyl)-1,3,5-triazine-2,4-diamine, and N2,N4, N6-trinitro-N2, N4, N6-tris(2,2,2-trinitroethyl)-1,3,5-triazine-2,4,6-triamine - 690.1 ± 5.9, 326.2 ± 13.6, 630.1 ± 6.1, 415.9 ± 9.3 kJ/mol, respectively. Based on these values, the energy equivalent of replacing the hydrogen atom and the azido group by trinitroethylamine and trinitroethylnitramine groups in triazine and azido-substituted derivatives of triazine. Calculations have shown that 6-azido-N2, N4-dinitro-N2,N4-bis(2,2,2-trinitroethyl)-1,3,5-triazine-2,4-diamine, and N2,N4, N6-trinitro-N2, N4, N6-tris(2,2,2-trinitroethyl)-1,3,5-triazine-2,4,6-triamine with an oxygen supply ratio greater than 1.0 can be used as the basis for designing compositions with a low aluminum content and with a specific impulse of 257-260 s.
