摘　　要：采用萃取、柱层分离等方法对中石化长岭分公司催化柴油、加氢精制柴油进行分离 ,并用GC/MS、LC/MS联用技术鉴定其结构 ,通过添加模拟化合物的方法考察不同化合物对柴油颜色安定性的影响。研究表明 :长岭分公司催化柴油的显色物质主要是烷基吲哚、氨乙醇基咔唑、苯基 -萘胺等深色化合物物质和结构复杂的酚类物质 ;柴油色度安定性主要与其中的不饱和烃、烷基吲哚、甲基咔唑、苯胺、苯酚等有关。Coloured compositions were separated from diesels produced from FCC unit and hydrocrack unit of Changling Branch SINOPEC by extraction and chromatogram. Their structure were mensurated by GC/MS、LC/MS. The infections of different compounds were tested by simulate experimentation. The result indicated that the coloured compositions of diesel produced from FCC unit were alkyl indole, ethanamine-carbazole,phenyl- naphthylamine and complicated hydroxybenzene. And color stability of diesel fuel were affected by unsaturated hydrocarbon, alkyl indole, methyl- carbazole, aniline and phenol.
