| 摘 要： | 本文通过将钯电解池安装在高灵敏度的电子自旋共振（ＥＳＲ）腔内，采用流动电解法现场检测到硝基苯在不同溶剂中电还原时硝基苯游离基的存在。在不同溶剂中，硝基苯游离基电子自旋共振产生的谱线分辨率不同，因而说明溶剂对硝基苯游离基有影响，且这些溶剂中钯电极上硝基苯的电还原必须经过硝基苯游离基中间体这一步。

| Abstract: | By means of a highly sensitive electrolytic cell installed in the ESR cavity,radical anion of nitrobenzene in the process of nitrobenzene electroreduction on palladium electrode in different solvent is dectected by flowing electrolytic system.The results show that in different solvent the discrimination of the ESR spectra are different,the solvent has an effect on nitrobenzene radical anion.The nitrobenzene electroreduction on Pd electrode must produce radical anion as an intermediate. |
