Cyclohexanone acidity
WebJul 10, 2024 · Cyclohexanone (C=O) is used as a raw material to produce ε-caprolactam and adipic acid, which are then converted to Nylon6 and Nylon66, respectively [ 4, 5 ]. The industrial production of C=O is achieved by three routes, namely, cyclohexane oxidation [ 6 ], phenol hydrogenation [ 7] and conversion of benzene into C=O [ 8] (Fig. 1 A). WebDec 1, 2024 · Cyclohexanone is considered to be the most valuable product of cyclohexane oxidation, and a high K/A ratio is desired for adipic acid synthesis. In conventional synthesis, KA oil is generated from cyclohexane and molecular oxygen via a cyclohexyl hydroperoxide intermediate ( Scheme 1) [ 30 ].
