Traditional catalyzed cyclohexane oxidation

A traditional catalyzed cyclohexane oxidation process consists of an oxidation and heat recovery section, a neutralization and decomposition section, a cyclohexane recovery section, a cyclohexanone separation and purification section, and finally a cyclohexanol dehydrogenation section. A simplified diagram of such a catalyzed cyclohexane oxidation process that is operated in a continuous mode is shown in the following ... 

DSM developed the noncatalyzed DSM Oxanone cyclohexane oxidation process in order to overcome the disadvantages of the traditional catalyzed cyclohexane oxidation process, namely, high cyclohexane and NaOH consumption figures and a large number of downtime hours. In addition, the DSM Oxanone process produces, after decomposition of CHHP, a KA oil with a KA ratio of more than 1.5 that requires a cyclohexanol dehydrogenation section with just a limited capacity.
