Pimelic acid

Pimelic acid

Pimelic acid is a dicarboxylic acid with the chemical formula C7H12O4. It is a white crystalline solid that is soluble in water and alcohol. Pimelic acid is used in the manufacture of polyamides, plastics, and adhesives. It is also used as a plasticizer and a corrosion inhibitor.

Chemical Structure

Pimelic acid has a linear structure with seven carbon atoms. The two terminal carbons are each bonded to a carboxyl group, making it a dicarboxylic acid. The remaining five carbons form a straight chain, with each carbon bonded to two hydrogen atoms.

Production

Pimelic acid can be produced by the oxidation of cyclohexanone or cyclohexanol. It can also be synthesized from adipic acid or glutaric acid.

Uses

Pimelic acid is used in the production of polyamides, which are used to make nylon and other synthetic fibers. It is also used in the manufacture of plastics and adhesives. As a plasticizer, pimelic acid is used to increase the flexibility and workability of plastic materials. As a corrosion inhibitor, it is used to protect metal surfaces from corrosion.

Safety

Pimelic acid is generally considered safe for use. However, it can cause irritation to the skin and eyes, and prolonged exposure can lead to respiratory problems. It is recommended to use personal protective equipment when handling pimelic acid.
