Versuchsvorschrift

In a vessel used in Example 55, 100 g. (819 m.moles) of 3,5-dimethylphenol, 5.68 g. (P=42.11) of 4-methyl-2-pentanone peroxide and 0.01 g. of 98% sulfuric acid were placed and the reaction was carried out at 100° C. for 20 minutes in the same manner as in Example 55 and analyzed. 3.67 g. (26.6 m.moles) of 3,5-dimethylcatechol and 1.52 g. (11.0 m.moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 89.3%.
