| Abstract: | The electrochemical reduction of 2-nitropropane to N-iso-propylhydroxylamine in sulfuric acid was investigated by linear scanning and cyclic voltammogram measurements.The results show that the Cu,Ni,Pb,graphite and Cu-Hg electrodes exhibit good electrochemical activities for 2-nitropropane reduction and the peak potentials are at-0.54,-0.56,-0.55,-0.64 and-0.9 V(vs.SCE), respectively.When the preparative electrolyses were conducted at a current density of 1 000 A/cm~2,the product yields and current(efficiency) obtained were higher than 85% and 67%,respectively.The Pb electrode was found to be the most suitable cathode material,which presented a yield of about 90% and a current efficiency of over 80%.The electrochemical reduction of 2-nitropropane on the Pb electrode is controlled by the diffusion process. |
