Energies of Combustion and Specific Heat Capacities of Diaminofurazan, Dinitrofurazan and Diaminoazofurazan
Energies of combustion and specific heat capacities of diaminofurazan(DAF), dinitrofurazan(DNF) and diaminoazofurazan(DAAzF) were determined. Energies of combustion for the three compounds are (-13043±119), (-6863±37) J·g-1 and (-12661±54) J·g-1, respectively. The corresponding standard molar enthalpies of formation (ΔfHmΘ) were obtained with the different combustion products. The values of specific heat capacities for the three compounds are (140.8±0.1), (236.8±0.2), (216.9±0.2) J·mol-1·K-1, respectively. Energy of combustion tends to rise with the decrease of oxygen content in molecule (DAF>DAAzF>DNF). Amino group contributes to increase energy of combustion, but nitro group has the opposite effect. As for the specific heat capacity, the change rule is opposite to energy of combustion.
