英文摘要: The processes of thermal decomposition of salvianolic acid B were studied by TG-DTG. The TG-DTG curves showed that the process of mass loss of the substance proceeded in two steps. The first step could be attributed to the expulsion of water in the temperature range of 305 similar to 373 K. The second step was corresponding to the large scale degradation of salvianolic acid B in the temperature range of 413 similar to 864 K. The activation energies E of thermal degradation process of three stages were obtained by Friedman method and Ozawa-Flynn-Wall method. According to 15 mechanism functions, the possible kinetic model of thermal degradation process was estimated to be Fn-F2-F1 through the multiple linear regression method.
