采用差热分析法与经典恒温方法相结合考察了双呋喃氟尿嘧啶(FD1)固体的分解动力学.实验结果表明,双呋喃氟尿嘧啶固体状态下很稳定,其在25℃条件下的降解速度常数及有效期分别为:400×10-7h-1、30年.
The decomposition kinetics of FDF solid was investigated by differential thermal analysis and classical thermostatic method.The experimental results show that DFU is stable under solid state and its degradation rate constant and expiration date at 25 ℃ Respectively: 400 × 10-7h-1, 30 years.
