The relative molar concentration ratios of c(superscript * subscript NO)/c(superscript * subscript NO2) changes as the temperature and pressure change. These results reveal that the two competitive reactions of C-NO2 homolysis (to form NO2) and isomerization may occur during the fast thermolysis of DNTF. NO formation from the cracking of furazan or furoxan rings may be limited by pressure.
结果表明，DNTF快速热裂解的主要产物CO、CO2、NO和NO2的相对摩尔浓度c与温度和压强有关，通过分析相对摩尔浓度比c(上标*下标 NO/c(上标*下标 NO2)随温度和压强的变化，揭示了DNTF中碳硝基C-NO2存在均裂生成NO2和异构化生成NO两条竞争分解的可能途径，同时压强可能抑制呋咱环和氧化呋咱环生成NO的可能性。

The calculated results with B3LYP/6-31G-DFT show:(1)the molecular total energy of benzofuroxan is lower than that of o-dinitrosobenzene;(2)the activation energy(Ea+=51.0kJ/mol)of forward reaction that benzofuroxan isomerises into o-dinitrosobenzene,is in agreement with the experimental(58.6kJ/mol)provided by reference,and the activation energy(Ea-=4.6kJ/mol)of back-ward reaction is very small.It is concluded thereby that benzofuroxan is more stable than o-dinitrosobenzene.In addition,the corresponding ab initio calculations at the level of HF/3-21G,HF/6-31Gand MP2/6-31G//6-31G were completed,and it was found that the calculated results by B3LYP-DFT method are superior to those from ab initio calculation.
