Hydrogen Peroxide → 2,6-Dimethylhydroquinone

Participants

Reaction Steps

In a vessel used in Example 52 were placed 100 g. (819 m. moles) of 3,5-dimethylphenol, 3.61 g. (36.1 m. moles) of 4-methyl-2-pentanone, 2.88 g. (50.8 m. moles) of 60 percent hydrogen peroxide and 0.01 g. of sulfuric acid, and the mixture was reacted at 110° C. for 20 minutes in the same manner as in Example 52. The reaction mixture was analyzed with gas chromatography. As products, 3.19 g. (23.1 m. moles) of 3,5-dimethylcatechol and 2.24 g. (16.2 m. moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 77.4 percent.
