Abstract: Process for preparing cyclohexanol and cyclohexanone by oxidizing cyclohexane with a gas containing molecular oxygen to form an oxidation mixture containing cyclohexyl hydroperoxide and treating the oxidation mixture with a metal salt in the presence of an aqueous solution of an alkali metal hydroxide for the decomposition of the cyclohexyl hydroperoxide is characterized in that the treatment of the oxidation mixture is effected at a temperature of about 70 .degree.C to about 115 .degree.C. When temperatures less than 70 .degree.C are employed the reaction velocity is too low. Temperatures in excess of about 115 .degree.C unexpectedly reduced the yield of the desired products. Thus the about 70 .degree.C to about 115 .degree.C temperature range is critical. The process produces cyclohexanol and cyclohexanone of sufficient purity for conversion in nylon 6 monomers without intervening purification.
