摘要
微波辐射下用二硫化碳萃取了神府煤并用GC/MS分析了萃取物,考察了萃取物的组成结构特征和部分组分的可能来源。结果表明:萃取物中的可检测成分为脂肪烃、烃基取代的芳烃和含杂原子的有机化合物,其中脂肪烃含量占绝对优势,且以7种C15-二环倍半萜烯同分异构体为主,可能来源于霍烷,检测出的链烃包括C18-C29正构烷烃和两种异构烷烃,烃基取代的芳烃中的芳环包括苯、萘和菲环,含杂原子有机化合物都含氧原子。
Under microwave irradiation, Shenfu coal was extracted with cabon disulfide and the extract was analyzed with GC/MS. The feature of composition and structure of the extract along with possible source of some species in the extract was examined. The results show that the detectable compounds are aliphatic hydrocarbons, alkyl-substituted arenes and heteroatom-containing organic compounds, among which aliphatic hydrocarbons are predominant, mainly consisting of C15-dicyclesesquiterpenes, which probably derived from hopanes; the chainalkanes detected include C18-C29 normal alkanes and two branched alkanes; aromatic rings in the alkyl-substituted arenas are benzene, naphthalene and phenanthrene rings and all the heteroatom-containing organic compounds detected contain oxygen atom （s）.
