摘　　要：含氮化合物的分离提取是实现煤基油高附加值利用的有效途径之一。介绍了固相萃取法、酸碱萃取法、离子液体萃取法和低共熔溶剂萃取法4种分离提取方法以及气相色谱法(GC)、气相色谱与质谱联用法(MS)、傅里叶变换离子回旋共振质谱法(FT-ICR-MS)和红外光谱法(FT-IR)四类组成鉴定方法的研究现状和优缺点。展望了技术发展趋势,指出含氮化合物的提取分离应加强固相萃取法中高效吸附剂的开发,加快离子液体和低共熔溶剂的研究制备,含氮化合物的分析鉴定将会更多采用傅里叶变换离子回旋共振质谱仪。The separation and extraction of nitrogen-containing compounds is one of the effective ways to achieve high value-added utilization of coal-derived oils.This paper introduces four separation and extraction methods,including solid-phase extraction,acid-base extraction,ionic liquid extraction,and low melting solvent extraction,as well as the research status,advantages and disadvantages of four composition identification methods,including gas chromatography(GC),gas chromatography mass spectrometry(MS),Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR-MS),and infrared spectroscopy(FT-IR).The development trends of technology were proposed.It is pointed out that the extraction and separation of nitrogen compounds should focus on developing high-efficiency adsorbents in solid phase extraction,accelerating the research and preparation of ionic liquids and low-melting solvents,and the analysis and identification of nitrogen compounds will increasingly use Fourier transform ion cyclotron resonance mass spectrometers.
