Production
2-Ethylhexanoic acid is produced industrially from propylene, which is hydroformylated to give butyraldehyde.
Aldol condensation of the aldehyde gives 2-ethylhexenal, which is hydrogenated to 2-ethylhexanal.
Oxidation of this aldehyde gives the carboxylic acid.
2-Ethylhexanoic acid forms compounds with metal cations that have stoichiometry as metal acetates. These ethylhexanoate complexes are used in organic and industrial chemical synthesis.
They function as catalysts in polymerizations as well as for oxidation reactions as "oil drying agents".
They are highly soluble in nonpolar solvents.
These metal complexes are often described as salts.
They are, however, not ionic but charge-neutral coordination complexes.
Their structures are akin to the corresponding acetates.
