2-Ethylhexanoic Acid Dealers

2-Ethylhexanoic acid (2-EHA) is an all-around aliphatic carboxylic acid. This is a peculiar feature. It is broadly used in industrial & specialty applications. With its eight-carbon backbone and a mild odor, it serves as a precursor to metal soaps, esters, plasticizers, corrosion inhibitors, and polymer-catalysts. Often supplied as a colorless, viscous liquid, 2-EHA combines favorable solubility in organic solvents with manageable handling properties, making it a cornerstone in formulations ranging from paints and lubricants to PVC stabilizers and coolant additives.

What Is 2-Ethylhexanoic Acid?

2-Ethylhexanoic acid (CAS 149-57-5), also known as octoic acid or α-ethylcaproic acid, is a branched monocarboxylic acid with the formula CH₃–(CH₂)₃–CH(C₂H₅)–CO₂H. It is a racemic mixture of the R as well as S isomers. It is peculiarly encountered as a clear to pale yellow liquid. Its melting point is about –59 °C (–74 °F), and it boils near 228 °C (442 °F) at atmospheric pressure. The density is roughly 0.903–0.906 g/mL, with a refractive index around 1.425 and a log P (~2.6–2.7), indicating moderate lipophilicity.

Water solubility is low (~1.4–2 g/L at 20 °C), with a pKa near 4.8. The vapor pressure is very low (<0.04 mbar at 20 °C), and vapors are heavier than air (vapor density ~5× that of air). Flash point is around 114 °C (237 °F), with auto-ignition at 310 °C (589 °F). OSHA and ACGIH exposure limits set the inhalable concentration at 5 mg/m³ (TWA).

It is classified as corrosive (Category 1), posing risks of severe skin burns and eye damage, with potential reproductive toxicity (H360). Occupational exposure must be strictly limited. Environmentally, it is harmful to aquatic life but is biodegradable; toxicity thresholds for algae, fish, and daphnia range from 41 to 110 mg/L.

Structure of 2-Ethylhexanoic Acid

2-EHA is a branched C8 carboxylic acid:

C8H16O2

A more systematic name is 3-ethylheptanoic acid (IUPAC: 2-ethylhexanoic acid). The branch at carbon 2 enhances lipophilicity compared to straight-chain analogs. 3D diagrams show the carboxyl group projecting from the branched center.

Handling and Storage

Handling:

Use in well-ventilated areas—local exhaust or fume hoods are recommended.

Prevent skin and eye contact: use gloves, goggles, face shields, and protective clothing per OSHA/EN standards.

Avoid inhalation of vapor/mist; respirators may be needed if the TLV is likely to be exceeded.

Storage:

Store tightly closed, upright in a cool (15–25 °C), dry, well-ventilated area; avoid heat sources and direct sunlight.

Keep away from oxidizers, strong bases, and reducing agents.

Use corrosion-resistant containers (e.g., stainless steel).

Segregate from incompatible substances and adhere to flammable/combustible liquid storage codes.

Accidental Release:

Evacuate area and use PPE.

Contain spill: absorb with inert material, collect in suitable containers, and dispose as hazardous waste. Prevent entry into drains or waterways.

Fire Fighting:

Use CO₂, dry chemical, or foam extinguishers. Please avoid water jet usage—may spread fire.

Firefighters should wear SCBA and chemical-resistant gear.

Combustion emits CO and CO₂.

Product Pack Size

Commercially available formats include:

100 mL, 250 mL, 1 L bottles (lab scale, e.g. Sigma-Aldrich, TCI).

Industrial drums (e.g., 210 kg), IBC totes (910 kg), or bulk tanks (Perstorp).

Custom flexibag or ISO-tank shipments for large-scale consumers.

Applications of 2-Ethylhexanoic Acid

• Metal Soaps / Driers: Forms metal 2-ethylhexanoates (e.g., Co, Mn, Al, Sn) used as catalysts in paints, inks, varnishes, and PVC stabilizers.
• Esters / Plasticizers: Condensed with alcohols to produce esters for PVB film, lubricants, and plasticizers.
• Polymer Catalysts: Tin(II) 2-ethylhexanoate is key in ring-opening polymerization (e.g., polylactide, PLGA). Aluminium and cobalt salts are also used.
• PVC Stabilizers: Acts as acid scavenger in conjunction with metal soaps to prevent HCl release during processing.
• Coolant / Corrosion Inhibitor: Inhibits corrosion in automotive heat-transfer fluids
• Processing Aid & Intermediates: Useful in organic syntheses—Biginelli reaction, alkynylation, esterification, etc.
• Lubricants & Engineered Fluids: As base acid or component for high-performance synthetic lubricants.
