中文摘要：

用热分析方法（TG,DTA）、热分解气相色谱和红外光谱等联合手段,对双酚A的二硝基取代产物和四硝基取代产物[2,2-二（4-羟基-3,5-二硝基苯基）丙烷和2,2-二（4-羟基-3-硝基苯基）丙烷]的热稳定性和热分解反应动力学进行了研究,发现它们的稳定性与硝基取代的数目有关,热分解具有失去一端并带走一个甲基的共同机理,然而热分解动力学方程形式不同分别是：dα/dt=50.90e^（-E/RT）（1-α）和dα/dt=59.06e^（-E/RT）（1-α）^3,从电荷分布均衡点出发对上述现象进行理论探讨.

英文摘要：

Thermal decomposition mechanism and thermal decomposition kinetics of 2,2-bis（4-hydroxy-3-nitrophenyl）- propane and 2,2-bis（4-hydroxy-3,5-dinitrophenyl）-propane have been investigated by means of DTA, TG, IR and thermal cracking gas chromatography. It was found that their thennostability was related to the number of nitryl replacement and the mechanism was similar. Their rate equations of thermal decomposition reaction were different and the reasons for this was discussed.
