| 英文摘要 | A simulation of the chemical transformations of methylphenanthrenes in sediment was performed using hydrous pyrolysis technique. the results indicate that isomerization is not the primary cause of the change in the MPl �� index. Rather, the degradation reaction of methylphenanthrenes to phenanthrene is one of the most likely causes reversing the trend of the MPl �� index with increasing the heating temperature. An unusual isomerization between 2-methylphenanthrene and 9-methylphenanthrene was also observed during the course of heating experiments. A plausible mechanism involving [1,5]-methyl shift was proposed for this isomerization reaction. |
