| 中文摘要: |
| 采用循环伏安法、计时电量法等电化学测试手段,研究了对硝基乙苯的电还原行为,研究表明乙基使峰电位负移,电极过程受扩散控制.测得扩散系数为0.71×10-4cm2/s、反应电子数5.5.恒电位电解电流效率为58%,产品收率43%. |
| 英文摘要: |
| The techniques such as cyclo voltammetry and chronocoulometry are used for the research of the characteristics of electroreduction of 1-ethyl-4-nitro-benzene.The experimental results show that peak potential is more negative than nitrobenzene,and the diffusion is the control step of the reduction.Diffusion coefficient is 0.71×10-4cm2/s,number of reaction was 5.5.Current efficiency 58%,the yield of 4-ethyl aniline was 43%. |
