Overview
Dodecanedioic Acid (DDDA) is a long-chain dicarboxylic acid primarily used as a monomer in polymer production. It is synthesized through the oxidation of cyclododecane or derived from renewable sources like vegetable oils. DDDA is valued for its ability to enhance the flexibility and durability of synthetic materials. Due to its bifunctional nature, DDDA is a key intermediate in the manufacture of high-performance polyamides and polyesters. Its applications span industries such as automotive, textiles, and coatings, where material resilience and chemical resistance are critical.
Physical and Chemical Properties
DDDA is a white, odorless crystalline solid with a melting point of 128-131°C. It exhibits moderate solubility in organic solvents like ethanol but is only slightly soluble in water. The compound's stability under high temperatures makes it suitable for polymer processing. Its molecular structure, featuring two carboxyl groups, enables it to form strong bonds with other monomers, contributing to the mechanical strength of resulting polymers. DDDA is non-reactive under normal conditions but may decompose at temperatures above 245°C.
Main Applications
DDDA is predominantly used in the production of nylon-6,12, a engineering plastic known for its resistance to abrasion and chemicals. This nylon variant is employed in automotive components, electrical connectors, and industrial coatings. The acid also serves as a precursor for adhesives, plasticizers, and lubricants. In the cosmetics industry, it is utilized in the synthesis of emollients and stabilizers. Additionally, DDDA-based polyesters are used in specialty films and fibers.
Safety and Storage
DDDA is generally low in toxicity but may cause mild irritation upon contact with skin or eyes. Proper handling requires gloves, goggles, and ventilation to minimize exposure. Spills should be cleaned immediately to prevent slipping hazards. Storage recommendations include keeping the material in tightly sealed containers away from moisture and oxidizing agents. Prolonged exposure to humid conditions can lead to clumping or reduced efficacy in polymer applications.
B2B Procurement Guide
When sourcing DDDA, prioritize suppliers who provide certificates of analysis (CoA) to confirm purity (≥99%) and low moisture content. Bulk buyers should negotiate pricing based on volume, as prices typically range between $5-$8 per kg. Consider suppliers with ISO certification or those specializing in bio-based DDDA if sustainability is a priority. Logistics planning should account for the material's stability, ensuring transportation avoids extreme temperatures or humidity.
