Perfluorododecanoic acid Chemical Properties,Usage,Production

Chemical Properties

Perfluorododecanoic acid (PFDoA, tricosafluorododecanoic acid, perfluoric acid, tricosafluorolauric acid) exists as solid white, fine crystals. Perfluorododecanoic acid may be incompatible with strong oxidizers. Upon decomposition, PFDoA can form carbon monoxide, carbon dioxide, and hydrogen fluoride.

Uses

Perfluorododecanoic acid is a twelve-carbon compound in the perfluoroalkyl family of chemicals. It is a byproduct of stain- and greaseproof coatings on food packages, furniture, and carpets. It is known to bioaccumulate in the environment, although research related to the toxicity of the chemical is scarce.

Definition

ChEBI: A fluoroalkanoic acid that is dodecanoic acid in which all of the hydrogens attached to carbon atoms are replaced by fluorines. It is a highly persistent, bioaccumulative breakdown product of stain- and grease-proof coatings on food packaging, soft furnish ngs and carpets.
