Oxidation of cyclohexanol to adipic acid
WebCyclohexanone and cyclohexanol are oxidized to adipic acid in high yield with aqueous 30% H 2 O 2 in the presence of H 2 WO 4 as a catalyst under organic solvent- and halide-free conditions. It is important that no solvent is used in order to achieve high reactivity in this heterogeneous reaction. WebDec 12, 2024 · Cyclohexanol is oxidized to cyclohexanone. The cyclohexanone reacts with the nitrous acid to yield isonitrosocyclohexanone producing 2-nitro-2-nitrosocyclohexanone by reaction with nitric acid. With attendant ring opening and uptake of water the latter compound is transformed into 6-hydroxyimino-6-nitro hexanoic acid.
