Abstract
- The heat of combustion and enthalpy of formation of bis(4 ″ -nitro[3,3 ′ :4 ′ ,3 ″ ]terfurazan-4-yl)-diazene (DNFNF) and (bis(4 ″ -azido-[3,3 ′ :4 ′ ,3 ″ ]terfurazan-4-yl)-diazene (DAzFNF) were first experimentally determined. It is found that the energy increment for replacing the nitro group with an azide group in the furazan cycle averages 290 kJ/mol and is close to the increment for replacing NO2 with N3 in trinitroethane. The dependence of the energy parameters of metal-free rocket propellants based on a mixture of ammonium perchlorate and DNFNF or DAzFNF with an active binder on the content of the high-enthalpy component in the formulation was studied by thermodynamic analysis.
