摘要：

Thermal decomposition of naringin was studied by TG-DTG/DTA The TG-DTG curve showed the process of mass loss of the substance proceeded in two steps The first step could be attributed to the expulsion of water of crystallization in the temperature range of 343 similar to 545 K The second step was corresponding to the large scale degradation of naringin in the temperature range 545 similar to 857 K The activation energy E of the thermal degradation process was obtained by Friedman method and Ozawa-Flynn-Wall method According to 15 mechanism functions, the possible kinetic model was estimated to be Fn-F2-Fl through the multiple linear regression method
