1,12-Dodecanedioic Acid (DDA)

The linear dicarboxylic acid 1,12-dodecanedioic acid (DDA) has a melting point of 125°C. It is virtually insoluble in water at room temperature.

DDA is formed by oxidative cleavage of cyclododecanol or cyclododecanone with nitric acid.

• the most important area of application of DDA is for production of polyamides such as polyamide 612 (VESTAMID® D) or specialty polyamides such as TROGAMID® CX, and of polyesters.
• DDA is also used in the production of hotmelt adhesives and coatings.
• DDA finds application in corrosion inhibitors.
• DDA also serves as a starting material in the fragrance industry.
