Combustionheats of FOX-7 and its five closed-loop derivativeswere determined and the standard molar enthalpies of formation (ΔfH°m) were obtained. The sequenceof combustion heat for the six compounds is DNDH > MDNZ > DNDX> DNDZ> DDNI > FOX-7. Combustion heat tends to rise with the increaseofthe number of C atoms in the molecule. Specific heat capacities weremeasured, and the standard molar heat capacities of the six compoundsare (176.59, 205.41, 207.76, 218.89, 217.76, and 215.40) J·mol–1·K–1, respectively. The specificheat capacity presents an opposite change rule with combustion heat.To the isomers and the introduction of hydroxyl group, the changerule is the same. Moreover, the introduction of hydroxyl group canmarkedly decrease the combustion heat and specific heat capacity. [ABSTRACT FROM AUTHOR]
