麻黄"上沫"成分的热分析TG-DTG-DSC及热解-GC-MS研究
Ephedra Scum Components by Thermal TG-DTG-DSC Analysis and Pyrolytic GC-MS Analysis
摘要
Abstract
The thermal properties of Ephedra scum was studied by TG-DTG and DSC methods while the components of Ephedra scum are further detected by pyrolytic GC-MS method.For Ephedra scum, the main temperature range of mass loss was 250 ～ 560 ℃.The fastest rate of mass loss was shown at 305 ℃ and 506.3 ℃.Two endothermic peaks were quite obvious respectively at 364.8 ℃ and 508.2 ℃.Ephedra scum is organic compound.The thermal decomposition product at 450 ℃ was analyzed by pyrolytic GC-MS, and twenty-eight chemical compounds were detected.关键词
