| Abstract: | 2, 3, 5-trimethylbenzoquinone (TMBQ) is a key intermediate for the synthesis of vitamin E. Using 1, 2, 4-trimethylbenzene (TMB) as a raw material to prepare TMBQ through one-step oxidation has high atomic economy and less three wastes. It is the next-generation key technology with the most application potential, which might significantly reduce production costs of vitamin E. For this technical route, the research progress in the synthesis of TMBQ from TMB by one-step catalytic oxidation in recent years was systematically reviewed. The effects of different catalytic systems on the selective oxidation of TMB were analyzed and summarized, the industrial application of direct oxidation technology of TMB to TMBQ was also prospected. |
