Infobox references

2-Octanol (octan-2-ol, 2-OH) is an organic compound with the chemical formula CH3CH(OH)(CH2)5CH3. It is a colorless oily liquid that is poorly soluble in water but soluble in most organic solvents. 2-Octanol is classified fatty alcohol. A secondary alcohol, it is chiral.

Production

2-Octanol is produced commercially by base-cleavage of ricinoleic acid.[8] The coproduct is a mixture of sebacic acid ((C8H16CO2H)2). Castor oil, which consists mainly of triglycerides of ricinoleic acid, is the main feedstock.[9] [10]

Uses

2-Octanol is mainly used as:

It can also be used as a chemical intermediate for production of various other chemicals:
