【摘要】：利用溶劑萃取和柱色譜等技術(shù)濃縮分離新疆寶明頁(yè)巖油柴油餾分中的堿性氮化物。以寶明頁(yè)巖柴油為原料,經(jīng)糠醛溶劑精制,初步得到富集堿性氮化物的抽出油。以抽出油為深度富集堿性氮化物的原料,采用柱色譜等分離方法,從抽出油中分離得到堿性氮化物。利用傅立葉變換紅外光譜儀(FT-IR)和氣相色譜-質(zhì)譜聯(lián)用儀(GC-MS)分別對(duì)富集的堿性氮化物進(jìn)行官能團(tuán)檢測(cè)和定性、定量分析。結(jié)果表明:新疆寶明頁(yè)巖油柴油餾分中的堿性氮化物經(jīng)溶劑精制和柱色譜等分離方法梯度富集后,堿性氮化物的質(zhì)量分?jǐn)?shù)由抽出油的12.08%提高到最終產(chǎn)物的69.48%,并在富集分離的產(chǎn)物中鑒定出60種堿性氮化物,其中主要為苯胺類、喹啉類和吡啶類化合物,各占25.85%,23.56%和16.52%。
[Abstract]:Basic nitride from diesel fraction of Baoming shale oil in Xinjiang was concentrated and separated by solvent extraction and column chromatography. Abstract oil enriched with basic nitride was obtained from Baoming shale diesel oil by furfural solvent refining. Basic nitride was separated from extract oil by column chromatography with extraction oil as raw material for deep enrichment of basic nitride. FT-IR (Fourier transform Infrared Spectrometer) and GC-MS (Gas Chromatography-Mass Spectrometry) were used to detect and qualitatively analyze the enriched basic nitride. The results showed that the basic nitrides in the diesel fractions of Baoming shale oil in Xinjiang were enriched by gradient method, such as solvent refining and column chromatography. The mass fraction of basic nitride increased from 12.08% of the extracted oil to 69.48% of the final product, and 60 kinds of basic nitride were identified in the products of enrichment and separation, mainly aniline, quinoline and pyridine compounds, accounting for 25.85% and 16.52% respectively.
