摘要

测定了三种化合物(DAF、DNF和DAAzF)的燃烧能和比热容。三种化合物的燃烧能分别为(-13043±119)、(-6863±37)J·g-1和(-12661±54)J·g-1。得到了不同燃烧产物对应的标准摩尔生成焓(ΔfHmΘ)。三种化合物的比热容分别为(140.8±0.1)、(236.8±0.2)、(216.9±0.2)J·mol-1·K-1。随着分子中氧含量的降低，燃烧能量呈上升趋势(DAF>DAAzF>DNF)。氨基有助于增加燃烧能量，而硝基则相反。比热容的变化规律与燃烧能量的变化规律相反。

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.
