Allyl-Substituted Furazanoazepines, Synthesis, Structure, Enthalpy of Formation, And Ballistic Efficiency

The synthesis of new energy-intensive compounds, 7-allyl-7 H -trifurazano[3,4-b:3',4'-f:3",4"-d]azepine ( AzAll ) and 7-allyl-7 H -difurazano[3,4-b:3',4'-f]furoxano[3",4"-d]azepine ( Az(O)All ) is described for the first time. The main parameters of the crystal lattice are determined by X-ray diffraction analysis and experimental data on the heats of combustion and enthalpies of formation of these two compounds are obtained . A thermodynamic analysis of the effectiveness of these compounds as components of solid composite propellants and gas-generating fuels is carried out. It is shown that the compounds under consideration have no prospects for use in solid composite propellants, but they are very effective as potential dispersants of solid fuels for gas generator engines .
