| Abstract: | The extracts from supercritical fluid extraction of Fengfeng bitminous coal were analyzed by thin-layer chromatography/flame inoization detection (TLC/FID) method. The oil (hexane soluble) was separated from the asphaltene (hexane insoluble benzene soluble) and preasphaltene (benzene insoluble)on a quartz rod coated with silica gel"Chromarod-SIL" using n-hexane/isopropanol (95/5) as the developing solvent. The asphaltene was then separ ated from the preasphaltene with benzene/isopropanol (80/20)deveioping solvent. The quantitation was carried out by peak area normalization. The results were compared with those obtained by sequential solvent extraction. |
