“…It is clear that the first value, 72.1 kJ/mol [45], is erroneous; also, it cannot be excluded that this value was given in kcal/mol. Although the second value, 241.0 kJ/mol [46], is closer to that obtained in this work, we suggest that our value based on experimental data, 287.7 ± 9.8 kJ/mol, is more reliable.…”

The gas-phase enthalpies of formation (D f H 298 ) of guanidine and its 10 amino and nitro derivatives were calculated using the isodesmic reaction method at the Gaussian-4 level of theory. The enthalpies of sublimation (D sub H 298 ) were estimated in the framework of the Politzer approach that combines the empirical equation for enthalpy of sublimation with the B3LYP/cc-pVTZ calculations of the electronic properties of the molecular surfaces. The enthalpies of sublimation of mono-, di-, and triaminoguanidine were also estimated using experimental data for their salts. On the basis of the calculated D f H 298 (g) and D sub H 298 values, the solid-phase enthalpies of formation were estimated for all guanidine derivatives. A predictive model confirms the available experimental data for guanidine, nitroguanidine, and some of their derivatives. The calculated value of solid-phase enthalpy of formation of high-nitrogen energetic compound 3,6-bis(2-nitroguanidino)-1,2,4,5-tetrazine is also in reasonable agreement with the reported experimental values.

“…Glyoxylic acid can be used to obtain many acyclic derivatives containing CQN bonds, namely, hydrazones and azomethines. In addition, guanidines, such as triaminoguanidine, diaminoguanidine (DAG), and aminoguanidine (AG), are significant components of high-energy materials, 18 biochemical molecules, 19 and complexes with special properties. 20 In recent years, our research group has investigated transition metal complexes of AG with various carboxylic acids, [21][22][23] including the structure and bioactivity of guanidine base salts, 24 and the formation of Schiff base metal complexes obtained from hydrazine derivatives.…”

“…TAGN exhibits a pressure‐dependent regression in which the self‐sustaining combustion is driven by heat released from condensed phase reactions which occur during decomposition [7]. GAP is a fuel‐rich, energetic binder which pairs well with TAGN to create a very fuel‐rich solid composite propellant [8].…”

The development and experimentation of a solid propulsion concept consisting of separate hydrogen‐rich solid propellant and solid oxidizer grains is presented. This system consists of an extremely fuel‐rich solid propellant, which, once ignited, undergoes a self‐sustaining decomposition to release fuel‐rich product gases, which are particularly rich in hydrogen gas. These relatively high‐temperature gases subsequently react with a solid oxidizer grain stored downstream. Progress in high‐nitrogen materials has allowed for the synthesis of fuel‐rich compounds that can store significant amounts of hydrogen, with little or no bound oxygen. With these new developments in propellant chemistry, a unique segregated propulsion system has been developed, creating an all‐solid propulsion system that combusts analogously to a reverse hybrid rocket system. Because of the physical separation of fuel and oxidizer, a higher level of safety is achieved which concurrently allows for the utilization of higher energy ingredients without the penalty of higher sensitivity. Theoretical performance calculations and experimental data have shown the potential for this system to compete with existing composite rocket propellants while having significant benefits in terms of safety, toxicity, and mission space. This paper presents a detailed overview of the conception, development, and testing of this propulsion system.
