Oxidation of cyclohexanol to adipic acid
WebThe cyclohexanol–cyclohexanone mixture is converted into adipic acid by continuous oxidation with 50% HNO 3 at about 75 °C using a copper-ammonium vanadate catalyst. The adipic acid is carefully purified by subjection to such processes as steam distillation and crystallization. The pure material has a melting point of 151 °C. WebMay 2, 1991 · The reaction chemistry of the oxidation of cyclohexanol to adipic acid under the influence of nitric acid has been critically reviewed. With the traditional process maximum selectivity towards adipic acid is reached at a high degree of HNO 3 consumption. Only under particular reaction conditions can the nitric acid consumption be reduced …
