摘要： 为了加深理解梗丝在卷烟叶组配方中的作用,对比研究了烤烟叶片和烟梗的化学组成以及它们在不同温度下的热裂解产物。一个改进后的热裂解装置被用来模拟卷烟的燃烧行为。采用热裂解仪研究了烤烟叶片和烟梗在大气环境中于300 ℃、600 ℃和900 ℃下的热裂解行为,并采用气相色谱-质谱联用仪对它们的热裂解产物进行分析。结果表明,烤烟烟叶和烟梗的热裂解产物种类随着热裂解温度的增加而增多;在相同热裂解温度条件下,烟叶的热裂解产物种类明显多于烟梗的热裂解产物。

Abstract: To further understand the effect of tobacco stems in tobacco blend, a detailed comparative study of chemical components of tobacco leaves and stems before and after combustion was carried out. Pyrolysis of tobacco leaves and stems was carried out by a CDS Pyrolyser 2000 coupled to a Finnigan 8000TOP Gas Chromatograph and a Voyager Mass Spectrometer (GC-MS). A modified apparatus of pyrolysis was used to emulate the behavior of combustion of cigarette. A set of pyrolysis conditions was also developed that approximated those occurring in the pyrolysis region of the burning cigarette. The conditions included heating the sample at 20 ℃/ms from 30 ℃ to 300 ℃, 600 ℃ and 900 ℃ in air, and their pyrolysates were analyzed by GC-MS. The results indicated that the values of routine chemical constituents in tobacco leaves and stems were obviously different. The pyrolysates belonged to numerous classes of compounds such as hydrocarbons, alcohols, phenols, aldehydes, ketones, nitriles, alkaloids etc. The kinds of pyrolysates of tobacco leaves and stems were positively related to the pyrolysis temperature levels. On the other hand, at the same temperature level, the types of the pyrolysates from the tobacco leaves were much more than those from the tobacco stems.
