Analysis of Pyrolytic Products of Geraniol by Pyrolysis-Gas Chromatography and Mass Spectrometry in Hyphenation
摘 要
采用裂解气相色谱-质谱法(Py-GC-MS)研究了香叶醇热裂解性质。以氦气为载气,将香叶醇样品分别在不同温度(300,400,500,600,650,700,800 ℃)下进行热裂解,将热解产物直接引入气相色谱-质谱仪进行定性和半定量分析。结果表明:在700 ℃时香叶醇完全裂解,裂解产物可达87种。根据主要的裂解产物和其相对含量的变化对香叶醇裂解机理进行初步探讨,为香叶醇在卷烟中的作用评价提供重要的理论依据。
Abstract
The pyrolytic properties of geraniol were studied by the hyphenation of pyrolysis-gas chromatography and mass spectrometry (Py-GC-MS). Helium was used as carrier gas, and pyrolysis of the geraniol sample was performed separately at temperatures of 300, 400, 500, 600, 650, 700 and 800 ℃. The pyrolyzates obtained were directly introduced into the GC-MS instrument and analyzed qualitatively and semi-quantitatively. It was found that geraniol was completely pyrolyzed at 700 ℃ and there were 87 pyrolyzetes obtained. Based on the main pyrolytic products obtained and on the change of relative contents of the products, a preliminary discussion on the mechanism of pyrolysis of geraniol was given, and a theoretical basis was proposed for the evaluation of action of the essence in the process of cigarette burning.
