摘　　要：采用PdCl2配位色谱法分离富集俄罗斯直馏汽油中的硫化物，用气相色谱-脉冲火焰光度检测器（GC／PFPD）与气相色谱-质谱（GC／MS）联用法对其中单体硫化物的结构进行研究，对直馏汽油中的硫化物采用面积归一法进行定量。结果表明，PdCl2配位色谱法是分离富集直馏汽油中硫化物的有效手段，鉴定出直馏汽油中含有四氢噻吩和四氢噻喃类硫化物，并检出了C5～C10的环硫醚系列。The sulfides in straight-run gasoline of Russia were employed to separate, enrich and evaluate by the ligand-exehange column chromatography using silica gel impregnated with palladium chloride. The concentrated sulfides were identified by GC/PFPD and GC/ MS. Major sulfides were quantified by area normalization method. The result shows that the ligand-exchange column chromatography is an effective method to separate sulfides in light oil. The sulfides in straight-run gasoline are mainly alkyl tetrahydrothiophene and alkyl tetrahydrothiopyran, and eyclosulfuricethers of C6-C10 are identificated.
