Review of A Cyclohexane Oxidation Reaction Using Heterogenous Catalyst
Priyank khirsariya,  Rajubhai Mewada
Cyclohexane oxidation is an important chemical reaction for industrial application. Cyclohexanol and cyclohexanon, also known as K-A oil, are important intermediate products for the production of nylon 6 and nylone 6,6 using oxidation of cyclone. A current process uses various metal salt. Commercially-practiced process is operated with very low conversion level, i.e. 4-6 % conversion due to severe selectivity problems. Due to higher reactivity of intermediate desired products, e.g. cyclohexanol and cyclohexanone, compared to cyclohexane leads to many byproducts formation and reduces selectivity drastically at higher conversion level. So it is restricted to operate at lower conversion level to achieve about 70-85% selectivity for K-A oil. Various metal salts like cobalt, gold, silver etc have been used as catalysts for cyclohexane oxidation. Due to stable nature of C-H bond results in higher activation energy required to carry out this reaction at higher temperature. Due to very less solubility of oxygen higher pressure is also desired. This paper discusses about the detail literature survey for cyclohexane oxidation reaction carried out using mainly oxygen or air as an oxidizing agent. With better understanding, it is expected that catalyst with better selectivity towards intermediate products will provide commercially feasible operation.
