    摘要: Six-membered ring carbocycles of the formula (II) can be prepared by ring hydrogenation of aromatic compounds of the formula (I) the definitions for which are given in the description, in a reaction system consisting of two liquid, immiscible phases in which elemental hydrogen is dispersed. The first phase consists of the aromatic compound (I) and, if necessary, a water-immiscible solvent. The second phase is essentially aqueous and comprises, colloidally dispersed therein, a hydrogenation-active metal as hydrogenation catalyst, and auxiliaries for stabilizing the colloidal catalyst. The process is carried out at from 50 to 180° C. and from 1 bar to 400 bar.
