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:

Flavor^[7]^[11]^[12]^[13]
low-volatility solvent : Diverses Resins (Paints & Coatings, Adhesives, Inks, etc.), Agrochemicals, Mineral Extraction, etc....^[14]^[15]^[16]^[17]
Defoaming agent : Pulp & Paper, Oil & Gas, Cement, Coatings, Coal, etc.
a frother in mineral flotation^[18]
wetting agent

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

Surfactants (ethoxylates, sulfates, ether sulfates, etc.),
Cosmetic emollients esters (palmitate, adipate, maleate, stearate, myristate, etc.),^[19]
Plasticizers (acrylates, maleates, etc.),
Pesticides: Dinocap ^[20]^[21]
Lubricants: Zinc dithiophosphate (ZDDP)
Fragrances (salicylate)
Used in the manufacturing of perfumes and disinfectant soaps^[22]
Used to prevent foaming and as a solvent for fats and waxes^[22]
Used to examine and control Essential Tremor and other types of involuntary neurological tremors^[22]
