Abstract

Energy-intensive compounds AzCH3, 7-methyl-7Н-trifurazano[3,4-b:3′,4′-f:3″,4″-d]azepine, and Az(O)CH3, 7-methyl-7Н-difurazano[ 3,4-b:3′,4′-f]furoxano[3″,4″-d]azepine, are extensively studied as potential dispersants in gas-generating fuels. 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 the formation of AzCH3 and Az(O)CH3 are obtained. A thermodynamic analysis of the effectiveness of these compounds in gas-generating fuels is carried out. It is shown that AzCH3 and Az(O)CH3 are very effective as potential dispersants of solid fuels for gas generator engines.

Keywords
