摘　　要：采用酸碱溶液萃取的方法将新疆低温煤焦油分离为酸性、碱性及中性组分。利用GC-MS色质联用仪及元素分析仪,对酸性组分和碱性组分的化学组成和结构进行定性定量分析。结果表明,新疆低温煤焦油酸性组分中共检测出质量分数不小于0.1%的化合物共74种,且全部为含氧化合物,其质量分数为95.4%;大部分为苯酚、C3-C4烷基酚、萘酚和茚酚。碱性组分中检测出质量分数不小于0.1%的化合物共57种,含氮化合物有57种,其质量分数为65.5%,主要由苯胺类、喹啉类、吲哚、吡啶、吖啶等氮杂环化合物组成。Through the separation of the group composition by acid-base extract,Xinjiang low-temperature coal tar has been divided into three different groups including acid-composition, base composition and neutral-composition. The acid-extract and base-extract were analyzed with GC/MS and elemental analysis. The results show that 74 kinds of compounds are analyzed from acid composition. All of them are oxygenated compounds and the content is 95. 4%. The main compounds in acid-composition are low-rank phenols, C3-C4 alkyl-phenols, naphthols and indenols. 57 kinds of compounds are in base composition and 55 nitrogenous compounds in them. The content of nitrogenous compounds is 65. 5%, mainly are phenylamine, quinoline, benzazole, pyridine and acridine.
