As important organic chemical materials, Cyclohexanol and cyclohexanone are widely used in many fields. Therefore the development of their new synthesis process has always been the focus of academies enterprises. In this paper, a preparation method for cyclohexanol and cyclohexanone by oxidizing cyclohexane is introduced, and the use of different catalysts in oxidation of cyclohexane is studied. The results show that currently there are many problems in this process, such as low conversion, low selectivity, high energy consumption and the problem of three wastes. Therefore, the developing trend of oxidation of cyclohexane is to improve conversion and selectivity, reduce cost and energy consumption, and decrease environmental pollution.
