摘要
本文用ＭＳ／ＭＳ技术研究抚顺老虎台气煤吡啶抽提残煤热解加氢产物中油段分的组成结构。先用硅胶色谱对该段分进行了分离，再用ＭＳ／ＭＳ技术进行表征。鉴定出氢化菲、氢化苯并芴等多环芳烃以及苯酚类多环芳烃等结构。这一结果为研究煤的基本结构单元的结构，乃至推导原始煤的大分子结构，提供了重要的科学依据。
The composition and structure of oil derived from hydrogenatedproducts of Fushun Laohutai gas coal pyridine-insoluble are discussed.A separationscheme of adsorption chromatography on silica gel was used to separate oil into sev-eral fractions. Two fractions,F_(11(2)),of them were characterized by MS/MS. Theresluts showed polynuclear aromatic hvdrocarbons(PAHs),such as phenanthrene,fluorene,and phenolic PAHs were presented in F_(11(2)) and F_(14) ,respectively. They pro-vide the scientific base for the studies of hasic structural units and macromolecularstructure of coal.
