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.

Abstract: Reaction mixtures which contain cyclohexyl hydroperoxide, cyclohexanol and cyclohexanone and are obtained by oxidizing cyclohexane with molecular oxygen, or a gas containing this, in the liquid phase at from 130 DEG to 200 DEG C. under from 5 to 25 bar are worked up by treatment with an aqueous alkali solution in the presence of a cobalt salt at elevated temperatures by an improved process wherein a phosphonic acid compound of the formula I where X is alkylene or 2 to 6 carbon atoms, R1 is -CH2PO3H and R2, R3 and R4 may be identical or different and are each -CH2PO3H, -CH2OH, hydrogen or alkyl of 1 to 4 carbon atoms, is concomitantly used.
