The Oxidation of Cyclohexane. Borrow eBooks, audiobooks, and videos from thousands of public libraries worldwide. Cyclohexane is a cycloalkane with the molecular formula C 6 H Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to al formula: C₆H₁₂.

A porphyrinic metal–organic framework (MOF), PCN(Fe), was found to exhibit sound activity and selectivity to cyclohexanone and cyclohexanol (known as KA oil) toward cyclohexane oxidation. Remarkably, hydrophobicity engineering of the MOF pore walls led to significantly enhanced activity and selectivity tCited by: A single-step air oxidation of cyclohexane, based on a new lipophilic catalytic system, leads to the production of adipic acid with excellent results. The catalytic activity outperforms previous reported catalytic systems for this reaction, and provides an environmentally benign alternative to an important industrial by:

The common cyclohexane oxidation products are cyclohexanol and cyclohexanone (other miscellaneous products may be formed in negligible amounts). The common oxidants are H2O2, ydroperoxide(TBHP) or other organic hydroperoxides, air, oxygen. To selectively obtain cyclohexanol, the oxidant H2O2 can be used.   The industrial oxidation of cyclohexane is usually performed in conditions that include high energy consumption, temperatures between and °C, and pressure of over 1 MPa. In addition, the conversion rate is controlled so that it remains below 10% to minimize undesired oxidation reactions and CO 2 formation.

Autoxidation of liquid cyclohexane utilizing pure oxygen to produce cyclohexanone, cyclohexanol, and their precursors is achieved in a medium of cyclohexane/water mixture.

Oxidation of cyclohexane. Oxford, New York, Pergamon. Cyclohexene oxide is produced in epoxidation reaction from cyclohexene. The epoxidation can take place either in a homogeneous reaction by peracids or heterogeneous catalysis (e.g.

silver and molecular oxygen).Chemical formula: C₆H₁₀O. The oxidation of cyclohexane is the main industrial process to obtain a mixture of cyclohexanone (Cyone) and cyclohexanol (CyOH) (referred to as KA oil of ketone and alcohol mixture), which are important intermediates in the production of Nylon-6 and Nylon [3,4,5], and are also raw materials for the production of caprolactam and adipic : Yuechao Hong, Jie Peng, Zhichao Sun, Zhiquan Yu, Anjie Wang, Yao Wang, Ying-Ya Liu, Fen Xu, Li-Xian.The selective oxidation of cyclohexane to cyclohexanol and cyclohexanone is an important chemical process and it has been paid more attentions recently.
