摘　　要：综述了近几年来离子液体在石油化工领域中萃取分离的应用,主要包括对于脂肪烃和芳烃的萃取分离、烷烃和烯烃的萃取分离、燃料油中的脱硫脱氮,并概述了离子液体在萃取分离过程中的萃取机理和影响因素。此外,针对离子液体回收难度较大的问题,概述了主要的回收方法,包括减压蒸馏、液液萃取和双水相分离等方法。结合离子液体的优势和存在的问题,对其工业化的应用提出展望。The applications of ionic liquids for extraction processes in petroleum and chemical fields were reviewed. It mainly included the separation of fatty hydrocarbon and aromatics,alkanes and olefins,desulfurization and denitrification in fuel oil. Meanwhile,the extraction mechanism and influence factors of ionic liquid in extraction process were summarized. In addition,for the problem of separation and recovery ionic liquids,the main recovery methods were also discussed,including vacuum distillation,liquid-liquid extraction and double water separation. Based on the advantages and problems of ionic liquids,the application of ionic liquids in industrialization was prospected.
