    摘要:

    测得了二氨基呋咱(DAF), 二硝基呋咱(DNF)及二氨基偶氮呋咱(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)和(12661±54) J·g-1,同时,计算得到了基于不同燃烧产物的标准摩尔生成焓(ΔfHmΘ)。三种化合物298.15 K时的标准摩尔热容分别为(140.8±0.1),(236.8±0.2),(216.9±0.2) J·mol-1·K-1。燃烧能随着分子中氧含量的增加而减少(DAF>DAAzF>DNF)。氨基基团有助于提高燃烧能,硝基则有负作用。对于比热容而言,三种化合物的变化规律与燃烧能相反。

    Abstract:

    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.
