Dodecanedioic acid (DDDA, DC12)
DODECANDY ACID
PRODUCT DESCRIPTION:
DC12 (1,12-dodecanedioic acid) is a long-chain dicarboxylic acid that is available as a high-purity, white powder.
Dodecanedioic acid, also known as DDDA or DC12, is a dicarboxylic acid with the chemical formula C12H22O4. It belongs to the family of aliphatic organicdicarboxylic acids and contains two terminal carboxylic acid functional groups (-COOH).
Dodecanedioic acid consists of a linear carbon skeleton with 12 carbon atoms. The carbon chain gives the acid flexibility and hydrophobic properties. Dodecanedioic acid can be obtained from various sources, mainly from petrochemical raw materials. It is produced by the microbial fermentation of alkanes. Diacid is a white, crystalline solid with a relatively high melting point. It is slightly soluble in water, but dissolves in organic solvents such as diethyl ether.
Corvay works with competitive and reliable manufacturers of dodecanedioic acid who also have REACH authorization. This makes Corvay a reliable partner in the supply chain of its customers. DDDA has several useful properties that make it valuable for various applications. It has excellent chemical stability, heat resistance and low volatility. It is also non-toxic and biodegradable.
Here are some of the most common uses of DDDA:
Polyamides (PA):
Dodecanedioic acid is used as an important raw material for the production of polyamides. It can be polymerized with hexamethylenediamine, for example, to form PA 6,12, which has excellent chemical resistance and good thermal stability. It also has low moisture absorption and therefore has excellent dimensional stability. PA 6,12 is used in the automotive industry, for coatings, adhesives and textiles, among other things.
Polyester:
The use of DDDA in polyester applications offers desirable properties such as improved strength, durability, chemical resistance and thermal stability.
Powder coatings:
Dodecanedioic acid is used as a cross-linking agent in powder coatings. Powder coatings provide durability, corrosion resistance and an attractive finish. DC12 contributes to the formation of cross-linked polymers during the curing process, which improves the properties of powder coatings.
Corrosion inhibitors:
DDDA is used as an anti-corrosion agent in various industries, including the oil and gas industry, metal processing and water treatment. It forms a protective film on metal surfaces and thus prevents corrosion.
Plasticizer:
DC12 can be esterified to produce dodecan diesters, which are used as plasticizers in polymers and resins. These plasticizers improve the flexibility, processability and durability of materials.
Body care products:
DDDA and its derivatives are used in the manufacture of personal care products such as shampoos, conditioners and skin creams. They can act as emollients, humectants and conditioning agents and have moisturizing and softening effects.
Chemical intermediates:
Dodecanedioic acid serves as a valuable chemical intermediate for the synthesis of various compounds, including pharmaceuticals, agrochemicals and specialty chemicals.
The applications of dodecanedioic acid are not limited to the areas mentioned above.
