Overview
Sodium 2-ethylhexanoate (CAS 16290-07-6) is a sodium salt of 2-ethylhexanoic acid. It is commonly used in industrial applications due to its properties as a catalyst, stabilizer, and corrosion inhibitor. The compound is hygroscopic and appears as a white to off-white powder or crystalline solid. This chemical is particularly valued in the polymer industry, where it facilitates polymerization reactions. Its solubility in water and polar organic solvents makes it versatile for various formulations, including coatings and adhesives.
Physical and Chemical Properties
Sodium 2-ethylhexanoate has a molecular weight of 166.19 g/mol and a molecular formula of C8H15NaO2. It typically decomposes at temperatures around 250-260°C. The compound is soluble in water and polar organic solvents, which enhances its utility in industrial processes. Its hygroscopic nature necessitates careful storage to prevent moisture absorption, which can affect its performance. The compound's stability under normal conditions makes it suitable for long-term storage when handled correctly.
Main Applications
The primary use of sodium 2-ethylhexanoate is as a catalyst in polymerization reactions, particularly in the production of synthetic rubbers and plastics. It also serves as a stabilizer in coatings and adhesives, ensuring consistent performance and durability. Additionally, the compound is employed as a corrosion inhibitor in metalworking fluids and other industrial applications. Its ability to form protective layers on metal surfaces helps prevent oxidation and degradation, extending the lifespan of equipment and components.
Safety and Storage
Sodium 2-ethylhexanoate should be handled with care to avoid inhalation or skin contact. Personal protective equipment (PPE), such as gloves and goggles, is recommended when working with this chemical. In case of exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Storage conditions should be cool, dry, and away from moisture and incompatible substances. Proper labeling and segregation from reactive materials are essential to ensure safety and maintain the compound's integrity.
B2B Procurement Guide
When procuring sodium 2-ethylhexanoate, B2B buyers should verify the purity and packaging specifications to meet their application requirements. Supplier certifications, such as ISO or GMP, can indicate reliable quality standards. The reference price range is approximately $20-$50 per kg, depending on purity and order quantity. Bulk purchases may offer cost savings, but buyers should also consider storage capabilities to prevent degradation over time.
