HCID 695602,6-Dimethylhydroquinone

Procedure

By following in the same manner as in Example 53, except that the amount of sulfuric acid was reduced from 0.01 g. to 0.001 g., and the reaction time was 30 minutes, 3.16 g, (22.9 m. moles) of 3,5-dimethylcatechol and 2.13 g. (15.4 m. moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 75.4 percent.
