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:
