WebMar 30, 2024 · It was found that the conversion after the first 2 h, the conversion of 2-methyl cyclohexanone is 63%. Until the end of the reaction after separation of the catalyst, the conversion remained unchanged. This confirms that no leaching of any active species of the catalyst in the reaction process. Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: C6H12 + O2 → (CH2)5CO + H2O This process forms cyclohexanol as a by-product, and this mixture, called "KA Oil" for ketone-alcohol oil, is the main feedstock for the production of adipic acid. The oxidation involves … See more Cyclohexanone is the organic compound with the formula (CH2)5CO. The molecule consists of six-carbon cyclic molecule with a ketone functional group. This colorless oily liquid has an odor reminiscent of acetone. Over time, samples … See more The great majority of cyclohexanone is consumed in the production of precursors to Nylon 6,6 and Nylon 6. About half of the world's supply is converted to adipic acid, one of two precursors for nylon 6,6.
