2Ethylhexanoic

2-Ethylhexanoic acid is a branched-chain carboxylic acid with the chemical formula C8H16O2. It is a colorless liquid at room temperature with a mild odor. The molecule consists of a six-carbon chain with an ethyl group attached at the second carbon atom. It is soluble in many organic solvents but only slightly soluble in water.

This compound is primarily used in the synthesis of metal salts, which serve as driers for paints, varnishes, and inks. These metal soaps, such as cobalt and manganese 2-ethylhexanoates, accelerate the oxidation and polymerization of drying oils, leading to faster drying times. It is also employed in the production of plasticizers, lubricants, and as an intermediate in the synthesis of other chemicals.

2-Ethylhexanoic acid can be produced through the dimerization of butyraldehyde followed by oxidation. It is generally considered to have low acute toxicity. However, prolonged or repeated exposure may cause skin and eye irritation. Environmental considerations are also associated with its production and use, and regulations exist regarding its discharge and handling.
