Heptadecafluorooctanesulfonic acid Usage And Synthesis
  • DescriptionHeptadecafluorooctanesulfonic acid 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 dioxide2. It is useful in the nitroaldol reaction in fluorous media, which is an important improvement of the chemo-selective addition of aldehyde3.
  • Chemical PropertiesPerfluorooctane 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.
  • UsesPerfluorooctane 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.
