Water → 4-Methoxycyclohexanone

Participants

Reaction Steps

0.5 g of borax and 0.5 g of water were mixed and 6 g of a catalyst which was moist with water (water content=50 %) and comprised 5% by weight of palladium on carbon were then mixed in. The resulting mixture was added to a solution of 100 g of p-methoxyphenol in 150 g of methylcyclohexane and this reaction mixture was hydrogenated in a stirred reactor at from 150 to 180° C. and from 3 to 8 bar of hydrogen pressure until no more hydrogen was absorbed. After a hydrogenation time of 72 minutes, 96.2% by weight of the p-methoxyphenol had reacted and p-methoxycyclohexanone had been formed in a yield of 83% by weight.
