  • Patent number: 6930209
    Abstract: A method for liquid phase oxidation of a cycloalkane compound is provided by which the cycloalkane compound intended to be oxidized mixes with water to form an azeotropic mixture, and then an oxygen enriched gas is introduced to perform an oxidation reaction. This method is particularly suitable for liquid phase oxidation of cyclohexane by using an oxygen enriched gas or pure oxygen, which not only enhances conversion rate and selectivity of the cyclohexane oxidation process but also improves process safety in the use of an oxygen enriched gas or pure oxygen for cyclohexane oxidation.
