A process for preparing cyclohexanol from benzene by:
- a) preparing cyclohexene by hydrogenating benzene in the presence of
a catalyst, and
- b) preparing cyclohexanol by hydrating the cyclohexene in the presence
of a catalyst, comprises:
- carrying out steps a) and b) in a reaction facility which has a
bottom region at the lower end,
- a top region at the upper end, and
- a reaction zone between the top region and the bottom region which
contains the catalyst according to steps a) and b),
- evaporating a portion of the benzene using the heat of reaction
in the reaction zone, condensing it in the top region and returning it to the reaction
zone, and
- withdrawing a reaction mixture containing cyclohexanol in the bottom region.
