摘　　要：采用循环伏安法和线性扫描法,以铜汞电极为工作电极,研究了α-硝基萘(NP)在硫酸介质中的电化学行为,探讨了扫描速度、底物浓度和温度等因素等对α-硝基萘电还原特性的影响.结果表明,α-硝基萘在铜汞电极上的还原反应是受扩散控制的不可逆反应.The electrochemical reduction of aromatic nitrocompounds plays an important role in the field of organic synthesis, and their reduction products are of great applied value. The electrochemical reduction of nitrobenzene has been studied before. But little work has been done on the electrochemical reduction of polycyclic aromatic nitrocompounds, especially for α-nitronaphthalene. Electrochemical reduction of α-nitronaphthalene in sulfuric acid solution on the amalgamated copper electrode was investigated in this paper using cyclic voltammetry and linear sweep voltammetry. The influences of scan rate, concentration and temperature on the electrochemical behavior of α-nitronaphthalene were discussed. Results showed that α-nitronaphthalene can be reduced at the amalgamated copper electrode, and the reduction of α-nitronaphthalene on amalgamated copper electrode was an irreversible process and controlled by diffusion.
