Overview
Eicosanedioic Acid, or 1,20-Eicosanedioic acid, is a long-chain dicarboxylic acid with the molecular formula C20H38O4. It is a white crystalline powder that is primarily used in industrial applications due to its stability and high melting point. The compound is synthesized through specific chemical processes and is valued for its role in polymer production and specialty chemicals. As a dicarboxylic acid, it features two carboxyl groups at the ends of a 20-carbon chain, making it useful for creating polymers with specific properties. Its long hydrocarbon chain contributes to its solubility in organic solvents and its utility in lubricants and coatings.
Physical and Chemical Properties
Eicosanedioic Acid is characterized by its high melting point of approximately 120-122°C, which makes it stable under typical industrial conditions. It appears as a white crystalline powder and is soluble in organic solvents like ethanol and acetone, though it has limited solubility in water. The compound's molecular weight is 342.52 g/mol, and its structure includes two carboxyl groups, which are reactive sites for polymerization and other chemical reactions. Its long hydrocarbon chain provides hydrophobicity, making it suitable for applications requiring water resistance or lubrication.
Main Applications
Eicosanedioic Acid is primarily used in the production of polymers, where it acts as a monomer or cross-linking agent. Its long-chain structure contributes to the flexibility and durability of the resulting polymers, which are used in coatings, adhesives, and specialty plastics. Additionally, it serves as a component in lubricants, where its stability and hydrophobic properties reduce friction and wear. The compound is also employed in the synthesis of specialty chemicals, including surfactants and corrosion inhibitors, due to its reactive carboxyl groups.
Safety and Storage
When handling Eicosanedioic Acid, it is essential to avoid inhalation, ingestion, and direct contact with skin or eyes. Personal protective equipment (PPE), such as gloves and goggles, should be worn to minimize exposure. In case of contact, rinse affected areas with plenty of water and seek medical advice if irritation persists. The compound should be stored in a cool, dry place away from direct sunlight and moisture to maintain its stability. Properly sealed containers are recommended to prevent contamination and degradation over time.
B2B Procurement Guide
For B2B buyers, it is crucial to verify the purity and specifications of Eicosanedioic Acid with suppliers before purchase. Bulk orders may offer cost advantages, but buyers should ensure that storage and handling requirements are met to maintain product quality. Procurement professionals should also consider the compound's intended application, as different grades may be required for polymer production versus lubricant formulations. Establishing long-term relationships with reliable suppliers can ensure consistent quality and availability.
