Abstract
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.
