    Abstract: Methods for continuously preparing cyclohexanone from phenol make use of a catalyst having at least one catalytically active metal selected from platinum and palladium. The process includes enriching phenol in a distillation fraction as compared to a subsequent fraction, wherein the subsequent fraction includes phenol and side-products having a higher boiling point than phenol. Distillation is carried out in a vacuum distillation column equipped with trays in the lower part of the column. In an upper part of the column, i.e., in the part above the feed inlet, packing material is present instead of trays in at least part thereof. The packing material has a comparable or improved separating efficiency, and provides a reduction of the pressure drop by at least 30%, preferably more than 50%, as compared to the case with trays in the upper part, under otherwise similar distillation conditions.
