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, 2.97 g. (29.7 m. moles) of 4-methyl-2-pentanone, 2.52 g. (44.5 m. moles) of 60 percent hydrogen peroxide and 0.01 g. of sodium bisulfate (NaHSO4.H2O), and the mixture was treated at 110° C. for 20 minutes in the same manner as in Example 52. As products, 2.19 g. (15.9 m. moles) of 3,5-dimethylcatechol and 1.25 g. (9.08 m. moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 56.1 percent.
