英文摘要 | Polychlorobenzenes can be reduced electrolytically to dichlorobenzenes by using either lead or copper as the electrodes in a MeOH/THF solution. Among the resultants of dichlorobenzenes, 1,4-dichlorobenzene is a major product that might be due to a low enthalpy of formation. A chlorine atom situated at the ortho position of another chlorine atom in the benzene ring is removed prior to others. However, the sequence of reactivities of the polychlorobenzenes for electroreducing by lead electrodes in this study is as follows: 1,2,3,4-C□H□Cl□>1,3,5-C□H□Cl□>C□HCl□~1,2,4,5-C□H□Cl□>1,2,3,5-C□H□Cl□~1 ,2,3-C□H□Cl□>1,2,4-C□H□Cl□>C□Cl□. 瓷� 1,2,3-C �� H �� Cl �� > 1,2,4-C �� H �� Cl �� >C �� Cl ��. |
