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. WebThe reaction is conducted in a distillation apparatus. As the reaction mixture is heated, the lower boiling products (cyclohexene, b.p. 830C, and water, b.p. = 100 oC) distill out and … WebIn this experiment an alkene (cyclohexene) will be prepared by dehydration of an alcohol (cyclohexanol) using an acid catalyst such as sulfuric acid or phosphoric acid.
