部分国内外卷烟主流烟气气相和粒相中挥发性、半挥发性成分的分析

分析了18种国内外品牌卷烟主流烟气中48种挥发性、半挥发性成分，研究了挥发性半挥发性化合物在气粒相的分配关系，结果表明:①气相中释放量较高的化合物分别是甲苯、柠檬烯、间二甲苯、乙苯和糠醛；粒相中释放量较高的化合物分别是丙二醇、乙酸、柠檬烯、2-呋喃甲醇和糠醛；②卷烟主流烟气中同一类挥发性、半挥发性成分的气相/粒相分配比随着其沸点的升高而减小；沸点相近的不同种类挥发性、半挥发性成分的气相/粒相分配比随着其极性的减小而升高；③卷烟主流烟气中挥发性、半挥发性成分的气相/粒相分配比与卷烟的类型没有明显的相关关系；④卷烟主流烟气中，大多数挥发性、半挥发性成分的气相/粒相分配比随着主流烟气焦油释放量的降低而增加，挥发性、半挥发性成分更容易向气相物转移。 

Analysis of volatile and semi-volatile components between gas phase and particulate phase of mainstream smoke from some brands cigarettes

The volatile and semi-volatile components in mainstream smoke (MS) from 18 brands commercial cigarettes were determined, and the distribution ratios of the 48 components between gas phase and particulate phase were discussed. The results indicated that: 1）tuluene, D-limonnene, m-xylene, ethybenzene and 2-furfural were predominant components in gas phase, and 1,2-propanediol,acetic acid, D-limonnene,2-furanmethanol and 2-furfural were predominant components in particulate phase, respectively; 2) the distribution ratios of the same kind of volatile and semi-volatile components in Ms were decreased with the increase of their boiling points, but the distribution ratios of them were not obvious relative with their polarities, and the different kind of components with similar boiling points in MS increased with the decrease of their polarities；3) the distribution ratios of the volatile and semi-volatile constituents between gas phase and particulate phase were not obviously relevant to the types of cigarettes; 4）the distribution ratios of the majority of the 48 components were increased with the decrease of the tar yield, and volatile and semi-volatile components were trended to transfer into gas phase with the decrease of the tar yield.
