2-cyclohexylidenecyclohexan-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Using the equipment from Example 15, 1500 ml cyclohexanone was charged to the flask with 100 g aluminum oxycarbonate. The flask was heated to an initial boiling point of 142 degrees C. Water evolved quickly and the temperature rose to 200 degrees C. in three hours. The fluid was decanted and distilled yielding unreacted cyclohexanone along with cyclohexylidene cyclohexanone and the higher condensation product C18H26O believed to be dicyclohexylidene cyclohexanone. The flask was heated to an initial boiling point of 142 degrees C rose to 200 degrees C The fluid was decanted distilled

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. dried at 120° C. for 20 hours 30 ml (25.5 g) of the catalyst thus prepared was then reduced to 350° C. the dehydrogenation reaction 3,972 g of reaction product
