利用等体积的二硫化碳‐丙酮混合溶剂对龙口（LK）和柳树河（LSH）油页岩进行超声萃取，对萃取物ELK和ELSH进行FTIR、GC／MS和DART‐MS分析。结果表明，LK和LSH油页岩的萃取率分别为2．18％和9．71％；ELK和ELSH中均存在大量的正构烷烃并具有明显的奇碳优势，ELK含有较多的异构烷烃、稠环芳烃和含氮有机化合物，而ELSH含有较多的环烷烃、烯烃和含氧有机化合物；DART‐MS分析表明ELK和ELSH中有大量分子量在520～850 Da范围内的化合物无法由GC／MS检测出，并且ELK中化合物的种类多于ELSH 。

Longkou (LK) and Liushuhe (LSH) oil shales were firstly extracted with isometric carbon disulfide/acetone mixed solvents under ultrasonic‐assistant condition ,then extracts ELK and ELSH were characterized by means of FTIR ,GC/MS and DART‐MS .The results show that the extract yields of LK and LSH are 2 .18% and 9 .71% ,respectively .Both ELK and ELSH contain abundant n‐alkanes ,and these n‐alkanes have obvious odd‐carbon number predominance .Nevertheless ,ELK contains more iso‐paraffins ,condensed aromatics and nitrogen‐containing organic compounds ,but ELSH contains more cyclanes ,alkenes and oxygen‐containing organic compounds .DART‐MS analysis shows that there are plenty of compounds with molecular weight between 520 and 850 Da in ELK and ELSH ,which could not been identified by GC/MS ,and the number of the compounds in ELK is more than that in ELSH .
