摘　　要：用气相色谱/质谱联用仪(GC/MS)分析馏程为340-360℃的新疆黑山煤液化重质油,检测出的主要成分为稠环芳烃及其衍生物,此外还有正构烷烃和少量含氧化合物。在超声辅助条件下,对液化重质油进行甲醇萃取,所得第一次甲醇萃取物用硅胶柱层析法分离。各洗脱馏分用GC/MS分析,其可测成分与直接检测相比更丰富,表明合适的预分离对提高GC/MS分析的灵敏度非常重要。A heavy oil （340 - 360℃） from direct liquefaction of Xinjiang Heishan coal was analyzed with gas chromatography/mass spectrometry （GC/MS）o Detected main components were polycyclic arenes and its derivatives along with normal alkanes and small amounts of oxygen - containing compounds. The heavy oil was extracted with methanol under ultrasonic irradiation, and the first extract was separated by silicagel column chromatography. The detectable compounds in subfractions by GC/MS were more abundant, indicating that preseparation was very important for increasing the sensitivity of GC/MS analysis.
