| Abstract: | The caffeic acid was pyrolysised in the atmosphere of nitrogen and nitrogen-oxygen mixture,respectively,by Simultaneous Thermal Analysis(STA) and the pyrolysis products were investigated with FT-IR.According to the pyrolysis behavior of caffeic acid,the pyrolysates under three temperature(280,300,415 and 515 ℃) in different atmosphere were analysized with GC-MS and 12 main compounds were identified. |
