実験手順

27 g of the catalyst prepared according to Example 1 were additionally impregnated with a solution of 0.81 g of K2SO4 in 10 ml of water and then dried at 120° C. for 20 hours. 30 ml (25.5 g) of the catalyst thus prepared were heated to 400° C. in a stream of hydrogen (10 l/hour), using the reaction tube described in Example 1, and were kept at this temperature for 68 hours. The oven temperature was then reduced to 350° C. and the dehydrogenation reaction was carried out without a carrier gas. 11.7 g/hour of the isomer mixture 2-cyclohexenylcyclohexanone and 2-cyclohexylidenecyclohexanone were thereby used. 3,972 g of reaction product containing 92.3% of o-phenylphenol and 0.5% of cyclohexylphenol were obtained in the course of 358 hours.
