摘要：

The thermal decomposition characteristics and kinetics of inositol were studied by DTA-TGA techniques. The curves of TGA and DTA of inositol at different heating rates (5, 10, 15, 20, 25°C · min-1) were acquired in nitrogen atmosphere. The kinetic parameters including the activation energy and pre-exponential factor of the thermal decomposition process for inositol were calculated by Flynn-Wall-Ozawa (FWO), Kissinger and Šatava-Šesták method, respectively. Moreover, the thermal decomposition mechanism of inositol was also studied. Results of this study show that the activation energy was found to be 208.03 kJ · mol-1, and logarithmic value of the pre-exponential factor logA was given to be 16.76. According to Šatava-Šesták method, the thermal decomposition mechanism of inositol was thought to be chemical reaction. Integral form of the most probable mechanism function of the decomposition process was obtained to be G(α)=(1-α)-1-1.
