Abstract: Adopt solvent refining and chemical caustic washing method to enrich and extract phenolic compounds from Fushun shale oil, then analyzed and identified with gas chromatographymass spectrometry (GC-MS). Fushun shale oil is extracted with N, N-dimethyl formamide (DMF) solvent, and the extracted phase of oil the initially enriched phenolic compound is obtained. The phenolic compounds are converted into phenol sodium salt dissolved in the inorganic phase by chemical caustic washing method, then reverse extract via acidification after separation to obtain phenolic compounds. Through the analysis and identification, the relative mass fraction of phenolic compounds in Fushun shale oil will be increased from 4.06% to 73.74% after enrichment. 49 kinds of phenolic compounds are identified in the extracted products, mainly for phenol class, including C3 phenol compounds with the highest mass fraction at 27.69%, and followed by C2 and C4 phenols at 19.18% and 15.96%, respectively.

摘要： 通过溶剂萃取及化学碱洗法富集-提取抚顺页岩油中的酚类化合物,由气相色谱-质谱联用仪(GCMS) 进行分析鉴定。抚顺页岩油经N,N-二甲基甲酰胺(DMF)溶剂萃取,得到初步富集酚类化合物的抽出相,采用化学碱洗法将酚类化合物转变为酚钠盐溶于无机相,分离后经酸化反抽提得到酚类化合物。经过分析鉴定,抚顺页岩油中的酚类化合物经富集后,质量分数可由4.06%提升至73.74%,在提取产物中鉴定出了49种酚类化合物,主要为苯酚类,其中C3苯酚类化合物质量分数最高,为27.69%,其次为C2及C4苯酚类,分别为19.18%和15.96%。
