摘要
用柱层析一步法分离富集胜利减二线油样中的酸性氮化合物,用1mol/L盐酸及3mol/L盐酸萃取碱性氮化合物,以色/质联用技术结合质谱、质量色谱、谱库检索及Lee保留指数对照等对各氮化合物进行定性鉴定。
The acidic nitrogen compounds in heavy petroleum(bp:335~500℃)were directly isolated by column chromatography and basic nitrogen compounds were extracted with hydro chloric acid 1mol.L~(-1)and 3mol.L~(-1),respectively.Subfractions were identified by the combining methods of MS,MC,library search and Lee's retention index data.
