Brief Overview
It is the organic compound with the formula CH 3 (CH 2 ) 3 CH(C 2 H 5 )CO 2 H. It is a carboxylic
acid that is widely used to prepare lipophilic metal derivatives that are soluble in nonpolar
organic solvents. 2-Ethylhexanoic acid is a colourless viscous oil. It is supplied as a racemic

Manufacturing Process
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 (2-EHA) acid is a chemical intermediate used in esters for Polyvinylbutyral
film plasticizers and synthetic lubricants, in metal salts for paint dryers, in automotive
coolants, PVC stabilizers, cosmetics and various other applications.
As a carboxylic acid with C8 carbon chain, 2-Ethylhexanoic acid is widely applied to various
applications. In the production of Polyvinylbutyral (PVB) plasticizers and synthetic
lubricants the acid is a major raw material for polyolesters. It is also used as a raw material
for paint dryers and Polyvinylchloride (PVC) stabilizers in the form of metal salts. In
cosmetics, 2-EHA is used to produce emollients. Other applications include corrosion

inhibitors in automotive coolants, catalyst for polymer production, raw material for acid
chloride and fragrances.
