Reaction Steps

In a vessel used in Example 52 were placed 100 g. (735 m. moles) of 2,3,5-trimethylphenol, 2.31 g. (23.1 m. moles) of 4-methyl-2-pentanone, 2.61 g. (46.0 m. moles) of 60 percent hydrogen peroxide and 1.0 g. of indium sulphate (In2 (SO4)3.9H2O), and the mixture was treated at 100° C. for 60 minutes. 2.16 g. (14.2 m. moles) of 3,4,6-trimethylcatechol and 0.64 g. (4.2 m. moles) of 2,3,5-trimethylhydroquinone were obtained. The yield of dihydric alkylphenols was 40.0 percent.
