Definitions
- Cyclohexanol is, according to: Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Volume A8, VCH Verlagsgesellschaft mbH, Weinheim, Germany, 1987, page 222, paragraph 6, an important intermediate in the production of adipic acid and Caprolacta, both of which Form monomers for the production of important polymers, such as polyamide 6 and 66. Cyclohexanol is also used as a solvent and cleaning agent and in the manufacture of plasticizers, insecticides and fragrances.
- the production of cyclohexanol from benzene is carried out in a reaction device which
- the reaction zone can be located within the distillation column.
- the reaction device between the bottom region and the reaction zone can contain a further zone (“separation zone”) which is free from catalysts according to steps a) and b) and which has a theoretical number of trays in the range from 5 to 50, preferably from 20 to 40 , in particular from 15 to 25.
- separation zone which is free from catalysts according to steps a) and b) and which has a theoretical number of trays in the range from 5 to 50, preferably from 20 to 40 , in particular from 15 to 25.
- mixtures of the catalysts mentioned for step a) and step b) can be used.
- a bifunctional catalyst can be used which catalyzes steps a) and b) at the same time.
- the quantitative ratio between benzene and water is determined by the stoichiometry of the reaction and also by the amount of water withdrawn in the bottom area. In particular comes in Quantity ratio of benzene to water in the range from 1: 2 to 5: 1 mol / mol, preferably from 1: 1 to 3: 1 mol / mol.
- the hydrogen required for the reaction can advantageously be added to the reaction device below the reaction device. If the reaction zone contains a separation zone, the hydrogen between the separation zone and the reaction zone can preferably be added to the reaction device.
- the quantitative ratio between benzene and hydrogen is determined by the stoichiometry of the reaction and also by the amount of cyclohexane withdrawn in the bottom region.
- a reaction mixture which contains cyclohexanol is removed in the bottom region.
- the selectivity of cyclohexanol in step a) and b), based on benzene, and the benzene content in the reaction mixture withdrawn in the bottom area can advantageously be regulated by means of the energy input into the reaction device, in particular in the bottom area.
