ABSTRACT Fireworks are probably the application of chemistry which resonates best with the general public. However, fireworks and (civil and military) pyrotechnic applications cause environmental pollution and thus have given rise to the development of new, environmentally friendly pyrotechnic compounds and formulations. Nitrogen-rich energetic materials, such as the derivatives of tetrazoles and tetrazines, are about to revolutionize traditional pyrotechnic compositions. This Review summarizes the sources of pollution in current formulations and recent efforts toward "green" pyrotechnics.

    ABSTRACT: A novel 8-N conjoined energetic compound 1-amino-tetrazolo-[4,5-b]tetrazole has been designed and investigated at the DFT-B3LYP/6-311++G** level of theory. The optimized geometry, vibration analysis, including thermochemistry and IR spectrum, NMR data, natural bond orbital and charges, HOMO-LUMO orbitals as well as electrostatic potential were calculated for inspecting the electronic structure properties and interactions of chemical bonds. Properties such as density, enthalpy of formation considering the enthalpy of phase transition and detonation performance have also been predicted. As a result, the detonation velocity and pressure of this compound are 8.90 km s(-1) and 33.83 GPa, respectively. The planar double rings (stable) with high-nitrogen structure (energetic), the high positive heat of formation (792.38 kJ mol(-1)) and the eminent performance, lead 1-amino-tetrazolo-[4,5-b]tetrazole to be a potentially very promising powerful energetic insensitive compound. In addition, the azido-cyclization kinetics of 1-amino-5-azidotetrazole forming the target compound have been investigated. In the gaseous state, the reaction barrier is 30.34 kcal mol(-1) and the reaction is endothermic as well as non-spontaneous under general conditions. The rate constants are evaluated over a wide temperature region from 200 to 1000 K using the transition state theory (TST) and the Arrhenius experience formula has been fitted as well. The theoretical researches on extended nitrogen chains could improve the synthesis of new high-nitrogen materials in the foreseeable future.

    ABSTRACT: A new family of energetic salts based on a new guanidinium cation containing a picryl moiety, N-(2,4,6-trinitrobenzylideneamino)guanidinium cation, was synthesized and well characterized by IR and multinuclear NMR spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and elemental analysis. The structures of N-(2,4,6-trinitrobenzylideneamino)guanidinium nitrate (1) and N-(2,4,6-trinitrobenzylideneamino)guanidinium 5-nitrotetrazolate (5) were confirmed by single crystal X-ray diffraction. Most of the salts decompose at temperatures over 180 °C. Furthermore, except for the salts 1 and 9, most energetic salts exhibit low impact sensitivities (20-40 J), friction sensitivities (220-340 N), and are insensitive to electrostatics. The detonation pressure values calculated for the energetic salts 1 and 3-9 range from 23.7 to 30.3 GPa, and their detonation velocities range from 7842 to 8394 m s−1. These values indicate that some energetic salts can be candidates for energetic materials that possess good thermal stability and low sensitivity.
