Beschreibung
Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. It is a very useful catalyst in chemical industry. It can catalyze the Intramolecular Hydroamination of Olefinic Sulfonamides in Fluorous Biphase System (FBS)
1. It can also catalyze ring-opening reactions of methylenecyclopropanes with aromatic amines, sulfonamides and alcohols in supercritical carbon dioxide
2. It is useful in the nitroaldol reaction in fluorous media, which is an important improvement of the chemo-selective addition of aldehyde
3.
Chemische Eigenschaften
Perfluorooctane sulfonate can exist as a liquid or a powder. It is soluble in water (NTP, 2013). Perfluorooctane sulfonate has the ability to react with strong oxidizing agents. Upon decomposition, PFOS can form carbon oxides, sulfur oxides, and hydrogen fluoride. Additional information related to the physical and chemical properties of PFOS are not currently available.
Verwenden
Perfluorooctane sulfonate (PFOS, 1-octanesulfonic acid, heptadecafluorooctanesulfonic acid, perfluorooctanesulfonic acid, 1-perfluorooctanesulfonic acid) is an eight-carbon compound in the perfluoroalkyl family of chemicals. Perfluorooctane sulfonate is used in a variety of applications, including textiles, leather products, cleaning products, and pesticides. Its main use was as a stain repellent on carpet, furniture, and other consumer products. 3M was the primary manufacturer of the chemical until it voluntarily phased it out in 2002 (USEPA, 2012). Perfluorooctane sulfonate is not manufactured any longer in the United States, but it can be imported for use in specific applications.
Application
Heptadecafluorooctanesulfonic acid may be used as an analytical reference standard for the determination of the analyte in water samples using solid-phase microextraction combined with high-performance liquid chromatography with electrospray-ion trap mass spectrometry.
Definition
ChEBI: Perfluorooctane-1-sulfonic acid is a perfluoroalkanesulfonic acid that is octane-1-sulfonic acid in which all seventeen of the hydrogens that are attached to carbons hvae been replaced by fluorines. It has a role as an antilipemic drug and a persistent organic pollutant. It is functionally related to an octane-1-sulfonic acid.
Allgemeine Beschreibung
Heptadecafluorooctanesulfonic acid belongs to the class of perfluorinated alkyl acids and is emerging as persistent organic contaminants in the environment.
Auswirkungen auf die Gesundheit
Exposure to unsafe levels of PFOA/PFOS concentrations through drinking water may result in health effects including developmental effects to fetuses during pregnancy, cancer, liver effects, immune effects and thyroid effects.
Environmental considerations
Perfluorooctane sulfonic acid (PFOS) is one of a group of related chemicals known as perfluorinated alkylated substances (PFAS). These are also called perfluorochemicals (PFCs). This group of chemicals is commonly used in a wide range of industrial processes and is found in many consumer products. PFOS can enter groundwater from multiple sources, including sewage treatment plants, industrial sites, landfills, and places where it is used in firefighting foam such as airports, firefighter training sites, and military installations. Fish and shellfish can take up PFOS from water contaminated with the chemical.
