    Abstract: 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.

    Extraction of metal-complex catalyst enriched stream comprises dissolving e.g. reaction products in reaction medium, distillating catalyst free stream of discharge, and separating high boiling and non-distilled components of discharge

    Abstract: Extraction of a metal-complex catalyst enriched stream comprises dissolving e.g. reaction products and by-products, in a reaction medium by an agent containing phosphorous and/or nitrogen atoms, modified organic metal complex catalyst; distillating the catalyst free stream of the reaction discharge; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream and recycling the retentate stream enriched, completely or partially into the metal-complex-catalyst. Extraction of a metal-complex catalyst enriched streams, obtained from the liquid discharge of a metal complex catalyst reaction comprises dissolving reaction products, by-products, non-converted educt, solvent, homogeneous or colloid in a reaction medium by an agent containing one or more phosphorous and/or nitrogen atoms, modified organic metal complex catalyst with a molecular weight of greater than 200 D and free ligands; distillating the catalyst free stream containing low boiling components of the reaction discharge at atmospheric pressure or low pressure; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream, by a membrane-separator device and recycling the retentate stream enriched with the metal-complex catalyst, completely or partially into the metal-complex-catalyst.
