2-Cyclohexen-1-one, 2,5,6-trimethyl- → 2,3,6-Trimethylphenol

Participants

Reaction Steps

1000 g of 2,5,6-trimethyl-2-cyclohexen-1-one is passed per hour per liter of catalyst at atmospheric pressure through an externally heated tube having a capacity of 250 cm3 and filled with a palladium/silica gel catalyst (0.2% by weight of palladium), the temperature being 300° C. The yield is 96% of 2,3,6-trimethylphenol. 4% of starting material is recovered and returned to the reaction.
