Summary: | PROBLEM TO BE SOLVED: To provide a new method for producing 2,3,5-trimethyl-p-benzoquinone capable of partially settling significant defects described in conventional technology level and relative to charged material cost, post-treatment cost and especially viewpoint of safety technology in industrially preventing degradation. SOLUTION: This method comprises carrying out the oxidation of phenol, at 20-120 deg.C, consisting of water and a 5-10C fatty alcohol or water, a 1-4C fatty alcohol and an aromatic hydrocarbon, in the presence of a catalyst system comprising a copper halide and a transition metal halide of a group consisting of Fe, Cr, Mn, Co, Ni and Zn or a rare earth element halide. |
