CAS:335-67-1 | Pentadecafluorooctanoic Acid

Products Description

Perfluorooctanoic acid, also known as Pentadecafluorooctanoic acid and Perfluoro - n - octanoic acid (PFOA), is an artificially synthesized perfluoroorganic compound. Its chemical formula is C₈HF₁₅O₂, its CAS number is 335 - 67 - 1, and its molecular weight is 414.07.

Physically, Perfluorooctanoic acid is a white crystal at room temperature, which may have an irritating odor. Its melting point is 52 - 56 ℃, and some data also show it as 54.3 ℃ or 55 - 60 ℃. Its boiling point is 189 ℃ or 192 ℃, and its density is 1.79 g/cm³. It is slightly soluble in water, has the characteristics of being hydrophobic and oleophobic, and is acidic. When the concentration is 1 g/L, the pH is 2.6 and the pKa value is 2.5. Due to the high electronegativity of fluorine, the carbon - fluorine bond is one of the covalent bonds with the largest bond energy in nature, so perfluorooctanoic acid is highly stable, antioxidant, and not easy to degrade.

Basic Info

Safety Information

Environmental hazards: It is not easy to degrade after entering the atmospheric environment. It can be migrated or transported from a long distance, and it reaches the ground with dry and wet settlement, or enters water or soil, and has been recognized as a new persistent pollutant.
Health hazards: It can be absorbed by the human body through the intake, inhalation, skin contact, etc., causing peroxysome reproduction in the human body to affect energy transmission and destroy cell membranes, thereby inducing diseases such as cancer and liver enlargement.

Uses

Surfactant: Perfluorooctanoic acid is used as a surfactant for the polymerization of fluoropolymer emulsions in industrial applications and is used to manufacture common consumer products such as Teflon.
Dispersant: used as a dispersant during tetrafluoroethylene polymerization and fluoroelastic rubber production, and is also a raw material and ore dressing agent for preparing water-enhancing and oil-repellent agents.
Other uses: It is also used for metal surface etching additives, whose sodium salt is a high-efficiency metal cleaning agent, and is also used to make surfactants.
