2-Ethylhexanoic Acid

Product details

2-Ethylhexanoic acid (2-EHA) is a dense, clear, colorless to yellow, high boiloing liquid, with a faint specific odour. It is immiscible with water, but miscible with almost all conventional organic solvents.Relative stable considering normal pressure and temperature. 2-Ethylhexanoic acid could be considered as biodegradable in soil and in aquatic systems, based on anaerobic and aerobic biodegradation studies.

Applications
Dyes and Paints
Catalyst in drying process (in paints, enamels, varnishers, printing inks)
Most of the siccatives are metal salts of the 2-EHA (metal soaps, the ethylexanoates or octoates) , they are also known as drying agents (siccatives).

In the timber industry it is used as wood preservative. The sodium salt of 2-ethylhexanoic acid, in mixture with other fungicides, is an active ingredient in wood preservative agent.
It is used in MEG based coolants (Organic Acid Technology or OAT's) where no silcates are used.It takes over the function as corrosion inhibitor in engine coolants.

You can find 2-EHA as stabilizeir in the plastic industry Which is based on barium, cadmium, tin or strontium.Despite the low thermal stability of PVC, processing at elevated temperatures is possible by adding specific heat stabilizers that stop the damage. During thermal stress on the PVC the EHA-salts intercept the arising hydrochloride. This acid can act as thermal and color stabilizers to alkyd resins.

Metal derivatives of 2-ethylhexanoic acid are used as plasticizers for polymers.
Often 2-Ethylhexanoic acid esters, based on  di-glycols, tri-glycols and polyethelene glycol, are also excellent plasticizers to PVC, nitrocellulose, chlorinated rubber and propylene.
2-EHA delivers excellent hydrolytic stability for developing emollients in cosmetics
Multifunctional UV absorbers can be prepared from 2-EHA as well as wetting agent emulusion. functional moieties and a polyalcohol core such as Penta.
