| 摘 要： | 室温下用等体积的二硫化碳／N-甲基-2-吡咯烷酮（CS2／NMP）混合溶剂对灵武煤进行超声辐射萃取。依次用正已烷、苯、氯仿和四氢呋喃作为展开剂对萃取物进行柱层析分离，得到馏分F1～F4，用气相色谱／质谱联用仪（GC／MS）分析各馏分。结果表明，烷烃高度富集于F1中，F3中稠环芳烃相对含量最高，F4的主要成分是合氧有机化合物。

| Abstract: | Lingwu coal was extracted with isometric carbon disulfide/N-methyl-2-pyrrolidinone （CS2/ NMP） mixed solvent under ultrasonic irradiation. The extracts were sequentially eluted with n-hexane, benzene, chloroform and tetrahydrofuran （THF）, affording fractions 1 to 4 （F1 to F4 ）, and each fraction was analyzed with GC/MS. The results show that saturated hydrocarbon are highly concentrated in the F1. Polynuclear aromatic hydrocarbon are the most abundant in the eluants with chloroform, and most components in the eluants with THF are oxygen-containing organic compounds. |
