| 摘 要： | 根据标样共注实验、保留指数对比、结合化合物结构及性质,对石油和沉积有机质中二苯并噻吩类含硫多环芳烃化合物的C1-和C2-烷基取代的二苯并噻吩化合物进行了鉴定,确定了其在HP-5MS色谱柱上的保留指数。研究结果纠正了多个前人鉴定有误的异构体,完整、系统地确定了4个C1-和14个C2-烷基取代二苯并噻吩系列化合物的保留指数和色谱质谱出峰顺序,初步探讨了石油及沉积有机质中烷基二苯并噻吩化合物的分布特征。

| Abstract: | Based on internal standards co-elution, retention indices comparison and molecular structure and chemical properties, a series of C1-and C2-alkylated dibenzothiophene isomers in oils and related sedimentary organic matters were firmly identified in this paper. The corresponding retention indices were also determined. This study corrected several compound peaks on mass chromatograms which were wrongly identified in previous publications. The elution order of all C1 and C2-dibenzothiophene isomers on GC column (HP-5MS) was systematically determined, and the distribution patterns of C1-and C2-alkylated dibenzothiophenes in petroleum and sedimentary organic matters were preliminarily discussed. |
