cyclohexanol

[¦sī·klō′hek·sə‚nȯl]
(organic chemistry)
C6H11OH An oily, colorless, hygroscopic liquid with a camphorlike odor and a boiling point of 160.9°C; used in soapmaking, insecticides, dry cleaning, plasticizers, and germicides. Also known as hexahydrophenol.

Cyclohexanol

 

an alicyclic alcohol having the structural formula

Cyclohexanol occurs as colorless crystals with a weak camphorlike odor. It has a melting point of 25.15°C, a boiling point of 161.1°C, and a density of 0.942 g/cm3 at 30°C. It is 4–5 percent soluble in water at 20°C and is miscible with most organic solvents. It dissolves many oils, waxes, and polymers.

Cyclohexanol forms all the derivatives that are characteristic of alcohols; these derivatives include alcoholates and esters. The catalytic oxidation of cyclohexanol with atmospheric oxygen produces cyclohexanone and, under more extreme conditions, adipic acid. Cyclohexanol is readily dehydrated to form cyclohexene, C6H10. Methods of producing cyclohexanol include the hydrogenation of phenol and the oxidation of cyclohexane, in the latter case usually in a mixture with cyclohexanone. Cyclohexanol is used as a solvent; it also serves as an intermediate in the production of caprolactam, the polymer of which is used in the production of polyamide fiber.
