These lipophilic metal-containing derivatives are used in many ways as catalysts in polymerizations, oxidation (drying agents), and organic synthesis. The high solubility of these metal complexes is attributable to the long hydrocarbon chain and the presence of a chiral center which leads to mixtures of enantiomeric complexes. These metal complexes, which exist as mixtures of several diastereoisomers, are often described as salts. They are, however, not ionic but charge-neutral coordination complexes. Their structures are akin to the corresponding acetates. 2-Ethylhexanoic acid (EHXA, 2-EHA) is an industrially important aliphatic carboxylic acid. 2-Ethylhexoic acid is used in the manufacture of 2-ethylhexanoic acid adhesives and sealant chemicals, corrosion inhibitors and anti-scaling agents, intermediates, lubricants and lubricant additives, paint and coating additives, and process regulators. 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 (2-EHA) is one of the flagship products within Perstorp Group which has the largest production capacity in the world.

The metallic salts of 2-ethylhexanoic acid are used as driers for odorless paints, inks, varnishes, and enamels. Cobalt a2-Ethylhexanoic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids 2-ethylhexanoic acid react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in 2-Ethylhexanoic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. 2-Ethylhexanoic Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.nd manganese are the most important driers.2-Ethylhexanoic acid (2-EHA )is widely used in esters for PVB film plasticizers and synthetic lubricants, in production of metal soaps for paint driers, in automotive coolants and PVC stabilizers.
