摘　　要：采用索氏萃取的方法,对高温煤焦油进行丙酮/CS_(2)萃取后,用GC/MS测定分析萃取产物的化学组成.结果表明,共检测出81种已知成分,包括64种芳烃类化合物,4种烷烃类化合物,3种酮类化合物,3种酯类化合物,2种醇类化合物以及5种其他类化合物.其中芳烃类化合物具有很高丰度.而其检测出的11种含N杂原子化合物和5种含S杂原子化合物,它们的丰度都不是很高.另外两种未知的化合物需要新的手段进一步分离检测.High temperature coal tar was extracted with acetone/CS_(2)by Soxhlet extraction.The chemical composition of the extracted products was determined by GC/MS.The results showed that 81 known compounds were detected,including 64 aromatic compounds,4 alkanes,3 ketones,3 esters,2 alcohols and 5 other compounds.Aromatic compounds have high abundance.The abundance of 11 compounds with N-heteroatom and 5 compounds with S-heteroatom were not very high.The other two unknown compounds need new methods for further separation and detection.
