Basic nitrogen compounds in diesel distillated from Xinjiang Baoming shale oil were concentrated by methods of solvent extraction refining and column chromatography,etc.The solvent refining method was used to separate diesel distillated from Xinjiang Baoming shale oil into extract oil.The solvent in the method of solvent extraction refining was furfural.The basic nitrogen compounds in the extract oil were concentrated preliminarily.Basic nitrogen compounds were obtained from the extract oil by column chromatography,and analyzed by Fourier transform infrared spectroscopy（FT-IR） and gas chromatography-mass spectrometry（GC-MS）.The results showed that basic nitrogen compounds in diesel distillated from Xinjiang Baoming shale oil were gradiently concentrated by methods of solvent refining and column chromatography.The percentage content of basic nitrogen compounds was increased from 12.08% in the extract oil to 69.48% in the product of enrichment,and 60 kinds of basic nitrogen compounds in the concentrated products were identified.The main components in the basic nitrogen compounds were aniline,quinoline and pyridine compounds,and their percentage contents were 25.85%,23.56% and 16.52%,respectively.
