采用DTA-TG-GC联用装置,在惰性气体(N_2)的动态气氛保护和程序控制温度的条件下,测定了3种葡萄糖衍生物的熔化热,通过DSC实验对其熔化热予以定量描述,并对其热分解机理进行了探讨。
The heat of fusion of three kinds of glucose derivatives was determined by DTA-TG-GC combined with the dynamic atmosphere protection of inert gas (N 2) and programmed temperature. The heat of fusion was quantitatively described by DSC. The mechanism of thermal decomposition was also discussed.
