摘要
A high-temperature coal tar collected from Xuzhou Coking Plant,Saint-Gobain Pipelines(Xuzhou) Co.,Ltd.was exhaustively extracted with petroleum ether(PE).The extract was sequentially eluted through silica gel with PE and PE/ethyl acetate(EA) mixed solvents(volume ratio 2:1) to afford two eluted fractions.The extract and eluted fractions were analyzed with gas chromatography/mass spectrometry.In total,14 arenols were detected,including phenol,cresols,xylenols,fluorenols,phenanthren-3-ol and pyren-1-ol.
