Preparation
Octadecanol - Octyl Alcohol is mainly produced industrially by the oligomerization of ethylene using triethylaluminium followed by oxidation of the alkyl aluminium products.
This route is known as the Ziegler alcohol synthesis.
An idealized synthesis is shown:
Al(C2H5)3 + 9 C2H4 → Al(C8H17)3
Al(C8H17)3 + 3 O + 3 H2O → 3 HOC8H17 + Al(OH)3
The process generates a range of alcohols, which can be separated by distillation.
The Kuraray process defines an alternative route to Octadecanol - Octyl Alcohol but uses C4 + C4 building strategy.
1,3-Butadiene is dimerized concomitant with the addition of one molecule of water.
This conversion is catalyzed by palladium complexes.
The resulting doubly unsaturated alcohol is then hydrogenated.
Octadecanol - Octyl Alcohol partitioning.
Octadecanol - Octyl Alcohol and water are immiscible.
The distribution of a compound between water and Octadecanol - Octyl Alcohol is used to calculate the partition coefficient, P, of that molecule (often expressed as its logarithm to the base 10, log P).
Water/octanol partitioning is a relatively good approximation of the partitioning between the cytosol and lipid membranes of living systems.

Production methods
Octanol exists in the form of free state or acetate, butyrate and isovalerate esters bitter in orange, grapefruit, sweet orange, green tea, violet leaves and other essential oils.
In industrial production, octanol can be obtained by the reduce of octyl aldehyde or the esterification of the octanoic acid in coconut oil.
Octanol can also be prepared through carbonyl synthesis with heptene-1 as the raw material.
Heptene, carbon monoxide and hydrogen can react in the presence of cobalt salt at 150-170 °C and under high pressure of 20-30MPa to generate aldehyde.
After cobalt removal, the above aldehyde is converted into primary alcohol by pressurized hydrogenation with the catalyst of nickel.
There has been mature production technology of this method in foreign countries.
