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 page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

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.
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.
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
Cyclohexylmethanol is an organic compound with the formula C 6 H 11 −CH 2 −OH. It is a cyclohexane ring functionalized with an alcohol , specifically a hydroxymethyl group. The compound is a colorless liquid, although commercial samples can appear yellow.
