HCID 695602,6-Dimethylhydroquinone

Procedure

By following the same manner as in Example 56 except that 0.013 g. of sodium hydrogen sulfate monohydrate (NaHSO4.H2O) was used, 3.42 g. (24.8 m.moles) of 3,5-dimethylcatechol and 1.66 g. (12.0 m.moles) of 2,6-dimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 87.4%.
