In paper, The electrochemical behavior of 1,2,3-trimethylbenzene (TMB) on Ti/nanoTiO2-Pt electrode was investigated by cyclic voltammetry and conditions of direct electrosynthesis of 2,3,5-Trimethylbenzoquinone (TMBQ) by electrolysis methods. The results showed that there are electrocatalytic activities of TMB on theTi/nanoTiO2-Pt Electrode, oxidative peak potential Ep is about 1.7 V and reaction irreversible process. And the current efficiency of TMBQ electrosynthesis is 47 % and the total percent conversion of TMB 58.8 % in ionic membrane electrolysis cell.
