| Production method | Vanillin is oxidized with hydrogen peroxide, then hydrolyzed, and methylated with dimethyl sulfate to prepare; or hydroquinone is oxidized with sodium dichromate and sulfuric acid to produce p-benzodiquinone, which is acetylated with acetic anhydride to obtain 1,2, 4-phlorotriacetate, and the latter is methylated with dimethyl sulfate to prepare the product. |
