Participants

Reaction Steps

In a vessel used in Example 52 were placed 100 g. (819 m. moles) of 3,5-dimethylphenol, 2.64 g. (22.0 m. moles) of methylphenylketone, 1.81 g. (31.9 m. moles) of 60 percent hydrogen peroxide and 0.01 g. of sulfuric acid, and treated at 110° C. for 20 minutes in the same manner as in Example 52. 2.10 g. (15.2 m. moles) of 3,5-dimethylcatechol and 1.04 g. (7.5 m. moles) of 2,6-dimethylhydroquinone were obtained. The yield of the dihydric alkylphenols was 70.9 percent.
