摘要：

Asphaltenes obtained from high-ash coal by precipitation with n-hexane were gamma-ray irradiated at different doses up to 320 kGy. After irradiation the vials were opened and submitted to chemical analysis using chromatography (PLC, GPC, GC), spectroscopic (MMR IR) and additional methods (elemental analysis. VPO). Based upon the class distribution obtained through preparative liquid chromatography (PLC-8) and the chemical analysis, a mechanism is proposed to explain the gamma-ray effects on the irradiation of asphaltenes.
