Procedure

With 10 g. (106 m. moles) of phenol were admixed the indicated ratios of 60 percent hydrogen peroxide and 4-methyl-2-pentanone in Table 5 and to the resulting mixture was added 0.070 g. of aluminum sulfate (Al2 (SO4)3.18H2O). The resulting mixture was reacted to 100° C. for 30 minutes in the same manner as in Example 1. Yields of catechol and hydroquinone are shown in Table 5.
