Cyclohexanol is the organic compound with the formula (CH2)5CHOH
Oxidation of cyclohexanol yields cyclohexanone.
Cyclohexanol is a colorless solid at room temperature, that rapidly melts into a viscous liquid upon gentle heating. It has a camphor-like odor and miscible with organic solvents.
Cyclohexanol is sold by chemical suppliers. Can also be bought online.
- C6H12 + ½ O2 → C6H11OH
This process co-forms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid. The oxidation involves radicals and the intermediacy of the hydroperoxide C6H11O2H.
- C6H5OH + 3 H2 → C6H11OH
This process can also be adjusted to favor the formation of cyclohexanone and cyclohexane.
- Make adipic acid and nylon
- Make cyclohexanone
Cyclohexanol is somewhat toxic: the TLV for the vapor for 8 h is 50 ppm. The IDLH concentration is set at 400 ppm, based on studies on the acute oral toxicity in animals.
Due to its high flash point of 67 °C, cyclohexanol is not very flammable and poses a moderate fire hazard.
Cyclohexanol should be kept in closed bottles, away from oxidizers and flames.
Should be mixed with a more flammable solvent and incinerated.
