Pentylbenzene → Phenol

Participants

Reaction Steps

All cyclohexylbenzene hydroperoxide cleavage reactions were carried out in a 100 mL round bottom flask equipped with a magnetic stir bar. Generally, about 14 g of crude oxidation product (see Example I), 0.4 g of internal standard (n-pentylbenzene), 0.05-0.5 g of catalyst and, optionally, about 10 mL of solvent were charged to the vessel. The reactor contents were stirred at room temperature to about 60° C. for about 30 minutes to about 2 hours, then sampled for analysis by gas liquid chromatography (glc). The product yields are corrected for the fact that only 90% of the hydroperoxide in the CHBHP feed is the correct hydroperoxide, i.e. ##STR2## Other isomeric hydroperoxides are incapable of cleavage to give the desired ultimate products, phenol and cyclohexanone.
