摘　　要：以丙酮作为溶剂,在微波辐射条件下对兖州煤和神府煤进行萃取,并利用气相色谱/质谱联用(GC/MS)技术对萃取物进行分析.结果表明:萃取物主要由芳烃和脂肪烃组成.在兖州煤的萃取物中芳烃主要是茶系化合物,而在神府煤的萃取物中检测出的芳烃以菲系为主;在兖州煤的萃取物中检测出多种异构烷烃,而在神府煤中只检测出一种异构烷烃.Yanzhou and Shenfu coals are extracted using acetone as solvent under microwave irradiation and the extracts are analyzed with GC/MS. The results show that the extracts consist mainly of arenes and alkanes; arenes in the extracts from Yanzhou coal are detected to occur mainly in the form of naphthalene and alkylnaphthalenes, while the detected arenes in extracts from Shenfu coal are dominated. The extracts from Yanzhou coal are detected to occur as a number of branched alkanes, while the extracts from Shenfu coal are detected to occur as only one branched alkane.
