ABSTRACT:
Reaction mixtures which contain cyclohexanol, cyclohexanone and cyclohexyl hydroperoxide and are obtained in the oxidation of cyclohexane with molecular oxygen, or with a gas containing this, in the liquid phase are worked up by a process in which the reaction mixture is hydrogenated in the presence of a noble metal catalyst at elevated temperatures and under superatmospheric pressure, the resulting mixture is treated with an aqueous alkali metal carbonate solution, and cyclohexanol and cyclohexanone are separated off by distillation.
