CATALYSED PHENOL HYDROGENATION |
摘要 |
The invention relates to a method for hydrogenating an aromatic compound. The invention in particular relates to a method for preparing cyclohexanone, cyclohexanol or a mixture thereof in a continuous way by catalytically hydrogenating phenol fed into a reactor comprising a supported hydrogenation catalyst, comprising a dopant selected from the group of alkali metal hydroxides, alkaline earth metal hydroxides, alkaline earth metal oxides, carbonates of alkali metals and carbonates of alkaline earth metals, and in which process during the hydrogenation of phenol continuously or intermittently water is fed into the reactor, the weight to weight ratio of water fed into the reactor to phenol fed into the reactor on average being 0.1 or less. |
