Abstract
In the process of phenol hydrogenation to cyclohexanol, improved yields of cyclohexanol are obtained by maintaining a hydrogen atmosphere throughout the entire operation. Of particular importance is that the hydrogen atmosphere is maintained during the time period when the nickel catalyst is allowed to settle and prior to decantation of the clear liquids.
