What is 2-Ethylhexanoic Acid?
2-Ethylhexanoic acid is a colorless to light yellow liquid with a mild odor. 2-Ethylhexanoic acid will burn though 2-Ethylhexanoic acid may take some effort to ignite. 2-Ethylhexanoic acid is slightly soluble in water. It is corrosive to metals and tissue. It is used to make paint dryers and plasticizers. Paint and varnish driers (metallic salts). Ethylhexoates of light metals are used to convert some mineral oils to greases. Its esters are used as plasticizers.
2-Ethylhexanoic acid can be used as an intermediate of paint and coating drying agent, alkyd resin modifier, production peroxide as a catalyst for polymerization reaction, lubricating oil ester and PVC stabilizer. It is widely used in the market.
2-Ethylhexanoic Acid Uses
- 2-Ethylhexanoic acid mainly used to prepare various metal salts as driers for coatings and paints, and its esters can be used as plasticizers and raw materials for carbenicillin.
- Most of 2-ethylhexanoic acid is converted into metal salts of zirconium, cobalt, molybdenum, zinc, etc., which are used as paint driers and heat stabilizers for polyvinyl chloride plastics; tin salts are used as additives for plastic pipes; barium salts, cadmium salt is used in plastic calendering products and stabilizers.
- 2-Ethylhexanoic acid and its esters are also used in medicine, fungicides, metal lubricants, cosmetics, etc. Its glycerides are excellent plasticizers.
- 2-Ethylhexanoic acid is the raw material of medicine carbenicillin. It is also used in the synthesis of many dyes and perfumes.
- 2-Ethylhexanoic acid is intermediate for paint and coating driers, used as alkyd resin modifier, used in the production of peroxides as a catalyst for polymerization reactions (such as PE), used as lubricating oil ester and PVC stabilizer.
- Organic synthesis, solvent.
- 2-Ethylhexanoic acid is a chemical substance that is harmful to health and has an irritating effect on the skin and mucous membranes. It emits a pungent acid mist when it is decomposed by heat. 2-Ethylhexanoic acid is used in the synthesis of many dyes and spices.

Preparation of 2-Ethylhexanoic Acid
Add 500g of isooctyl alcohol, 258g of potassium hydroxide, 10g of zinc formate to a 2000ml autoclave. The reactor is replaced with nitrogen twice to exhaust the air from the system. After sealing, the reaction is carried out at 230°C and 2Mpa. The reaction proceeds. After 6h, keep holding for 50min, then lower the temperature to below 160℃, then reduce the pressure in the kettle to normal pressure, add 400ml of distilled water and stir for 30min to obtain an aqueous solution of potassium isooctanoate.
Transfer the potassium isooctanoate aqueous solution to the flask, slowly add 212g of 94wt% formic acid solution under stirring, control the reaction temperature to 60℃, react for 30min, transfer to a separatory funnel, stand for 30min, separate the water phase by layer, Simple concentration to obtain potassium formate solution (the solution can be sold directly as a commercial product or concentrated to a certain concentration such as 74%); the oil phase is washed twice with 60g distilled water to obtain crude isooctanoic acid, and the unreacted alcohol is removed by vacuum distillation, and the product is obtained by rectification The finished product of isooctanoic acid is 542 g, and the weight yield based on isooctyl alcohol is 108.4%, and the molar yield is 97.92%.
Add 250g of isooctyl alcohol, 172g of caustic soda, 1.6g of zinc acetate, and then add 250g of isooctyl alcohol to a 2000ml autoclave. After condensation, it is discharged outside. When there is no hydrogen evolution in the reaction, the pressure is maintained for 40 minutes, the temperature is lowered to below 120°C, then the pressure in the kettle is reduced to normal pressure, 500 ml of distilled water is added, and the mixture is stirred for 30 minutes to obtain an aqueous sodium isooctanoate solution.
Add 350g of distilled water to another flask, slowly add 250g of concentrated sulfuric acid under stirring, keep the temperature in the flask not exceeding 80°C, slowly pour the reactants in the autoclave into the flask, control the reaction temperature to 70°C, react for 40min, and move to Separate funnel, keep the temperature at rest for 1 hour, and then separate the water phase to remove the water phase. After the water phase is treated, refined sodium sulfate is recovered; the oil phase is washed twice with distilled water at about 70°C to obtain crude isooctanoic acid, and the unreacted alcohol is removed by distillation under reduced pressure , Rectification to get the finished product of isooctanoic acid with a yield of 105%.
What is Metal Ethyl Caproate?
2-Ethylcaproic acid forms a compound with metal cations, and its stoichiometry is metal acetate. These ethylcaproic acid complexes are used in organic and industrial chemical synthesis. They act as catalysts in polymerization and “oil desiccants” in oxidation. They are highly soluble in nonpolar solvents. These metal complexes are often described as salts. However, they are not ionic, but charge neutral coordination compounds. Their structure is similar to that of the corresponding acetate.
Examples of metal ethyl caproate
- Bis (2-ethylcaproic acid) hydroxy aluminum, used as thickener
- Tin (II) Ethylhexanoate (CAS 301-10-0), a catalyst for polylactide and poly (lactic acid co glycolic acid)
- Cobalt (II) Ethylhexanoate (CAS 136-52-7), a drying agent for alkyd resin
- Nickel (II) Ethylhexanoate (CAS 4454-16-4)
