2-Ethylhexanoic acid – Properties
2-Ethylhexanoic acid is a colorless, oily liquid with a mild characteristic odor. It is slightly soluble in water (1.4 g/L at 25°C) and miscible with most organic solvents (e.g., ethanol, ether, acetone). As a branched-chain carboxylic acid, it exhibits good thermal stability and is widely used as a versatile chemical intermediate for producing metal salts, esters, and other derivatives.

2-Ethylhexanoic acid – Application

  • Coatings & Paints: Key raw material for metal driers (cobalt, manganese, zinc salts) to accelerate film curing; used as a modifier for alkyd resins.
  • Plastics: Precursor for PVC heat stabilizers (zinc, calcium salts) and plasticizers.
  • Lubricants: Used to synthesize polyol ester base oils for high-temperature synthetic lubricants; metal salts act as anti-wear additives.
  • Polymers: Catalyst component (e.g., tin salts) for polyurethane and polyester polymerization.
  • Pharmaceuticals: Intermediate for manufacturing carbenicillin and other APIs.
  • Other: Cosmetic emollients, metal extractants, and textile auxiliaries.

2-Ethylhexanoic acid – Package and Storage

  • Package: Standard packaging in 180-900kg drum, custom packaging available.
  • Storage: Keep in cool, dry, well-ventilated areas at below 30°C, tightly sealed. Avoid direct sunlight, moisture, and contact with alkalis/oxidizing agents. Shelf life: 24 months in unopened original packaging.
