2-ethylhexanoic acid, also called 2-EHA, is used in the following products: coating products, laboratory chemicals, lubricants and greases, and metalworking fluids.
2-ethylhexanoic is used in anti-freeze products, indoor use as a processing aid, indoor use in close systems with the minimal release (e.g., cooling liquids in refrigerators, oil-based electric heaters), and outdoor use in close systems with minimal release (e.g., hydraulic liquids in automotive suspension, lubricants in motor oil and brake fluids).
2-Ethylhexanoic is widely used in esters for PVB film plasticizers and synthetic lubricants, metal soaps for paint driers, and automotive coolants and PVC stabilizers.
Other application areas of 2-Ethylhexanoic include wood preservatives, catalysts for polyurethane, and pharmaceuticals.
Automotive
2-EHA is used in the production of corrosion inhibitors for automotive coolants.
Coatings
2-Ethylhexanoic as a monomer synthesizes alkyd resins, providing improved yellowing resistance than standard fatty acids.
2-Ethylhexanoic is particularly suitable for stoving enamels and two-component coatings.
2-Ethylhexanoic is also used as a raw material for metal-based paint driers.
Lubricants
2-Ethylhexanoic is a major raw material for polyol esters used in synthetic lubricants.
Personal Care
2-Ethylhexanoic is used to produce emollients in the cosmetic industry.
2-ethyl hexanoic acid is used to make emollients and skin conditioners for cosmetic purposes.
2-ethyl hexanoic acid is frequently used in hair care products, body lotions, hand creams, foundation, concealer, and face creams.
Other
Polyvinyl butyral plasticizer, which is a major constituent for the production of safety glass and sheet material for construction purposes, is produced from 2-Ethyl Hexanoic Acid
Polyvinyl butyral (PVB) plasticizers and polyvinylchloride (PVC) stabilizers are produced in the form of metal salts.
Other applications include polymer production catalysts, raw acid chloride material, and fragrances.

2-Ethylhexanoic acid is produced industrially from propylene 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
