摘要：

Hydroxylated thiophenic compounds in a coal liquid were determined by capillary column gas chromatography and gas chromatography/mass spectrometry. Capillary column gas chromatography with two new selective stationary phases, a biphenyl polysiloxane and a smectic liquid crystalline polysiloxane, were used. Several compounds were positively identified by comparison of their retention times with those of newly synthesized standard compounds. Two groupings of hydroxylated thiophenic compounds were observed in this sample. The first group is composed to hydroxybenzothiophenes and (hydroxyphenyl)thiophenes, while the second group contains hydroxydibenzothiophenes and (hydroxyphenyl)benzothiophenes.
