実験手順

500 ml of catalyst were introduced into a fluidized-bed reactor having a capacity of 0.7 liter. The catalyst contained 0.25% by weight of platinum on a magnesium aluminum spinel carrier and had a particle size of from 0.2 to 0.6 mm and a BET specific surface area of 125 m2 /g. The temperature of the reactor was brought to 275° C., and the mixture which was preheated to this temperature and consisted of 200 liters/hour of nitrogen and 20 liters/hour of hydrogen was passed in. 60 g/hour of gaseous 2,6-dimethylcyclohexanol were passed continuously through the fluidized catalyst bed produced in this manner. The reaction product was obtained by cooling the exit gases, and was distilled. 100 g of 2,6-dimethylcyclohexanol were converted to 90.5 g (yield: 95% of theory) of 2,6-dimethylphenol.
