摘要：

Asphaltols obtained by benzene precipitation of coal-derived liquids extracted with hot pyridine were purified by preparative liquid chromatography and X-ray irradiated to different doses. The irradiated product was analyzed using chromatographic and spectroscopic methods. The results obtained show that asphaltenes are degraded to resins.
