Аннотация

7-Propargyl-7H-difurazano[3,4-b :3′,4′-f]furoxano[3″,4″-d]azepine (Az(O)Prg) and 7-propargyl-7H-trifurazano[3,4-b :3′,4′-d :3″,4″-f]azepine (AzPrg) as potential dispersants of solid fuels for gas-generating engines were synthesized for the first time. Their molecular structure, enthalpies of combustion and formation are determined. The relative aircraft flight range is estimated when using Az(O)Prg and AzPrg as fuel dispersants.
