HCID 695602,6-Dimethylhydroquinone

Procedure

By following in the same manner as in Example 53, except that 1.10 g. of strong acidic sulfonic type ion exchange resin Amberlist 15 (manufactured by Rohm & Haas Co.) was used instead of sulfuric acid, 2.88 g. (20.9 m. moles) of 3,5-dimethylcatechol and 1.74 g. (12.6 m. moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 65.9 percent.
