Cyclohexanol is the organic compound with the formula HOCH(CH 2) 5. The molecule is related to cyclohexane by replacement of one hydrogen atom by a hydroxyl group . [ 4 ] This compound exists as a deliquescent colorless solid with a camphor-like odor, which, when very pure, melts near room temperature.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The "(s)" annotation indicates equilibrium temperature of vapor over solid. Otherwise value is equilibrium temperature of vapor over liquid. log 10 of Cyclohexane vapor pressure.
Cyclohexane has two crystalline phases. The high-temperature phase I, stable between 186 K and the melting point 280 K, is a plastic crystal, which means the molecules retain some rotational degree of freedom. The low-temperature (below 186 K) phase II is ordered.

Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [11]. C 6 H 12 + O 2 → (CH 2) 5 CO + H 2 O. 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.
Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam. [8] The oxidative cleavage of cyclohexene gives adipic acid. Hydrogen peroxide is used as the oxidant in the presence of a tungsten catalyst. [9] 1,5-Hexadiene is produced by ethenolysis of cyclohexene. Bromination gives 1 ...
Adipic acid is produced by oxidation of a mixture of cyclohexanone and cyclohexanol, which is called KA oil, an abbreviation of ketone-alcohol oil. Nitric acid is the oxidant. The pathway is multistep. Early in the reaction, the cyclohexanol is converted to the ketone, releasing nitrous acid: HOCH(CH 2) 5 + HNO 3 → O=C(CH 2) 5 + HNO 2 + H 2 O
