| 释义 |
The dominant chemical compound is perfluorononanoic acid (PFNA) at 74% by weight, followed by the 11 carbon perfluoroundecanoic acid (20%), and the 13 carbon perfluorotridecanoic acid (5%).[2] Surflon S-111 is synthesized in Japan by oxidizing a mixture of fluorotelomer olefins.[2] Fluorotelomer olefins are synthesized using a telomerization of tetrafluoroethylene taxogens (monomers),[1][3] followed by an ethylene insertion.[3] The olefin is oxidized, removing one carbon to yield products with an odd number of carbons[2] with even-lengthed fluorocarbon chains plus a carboxylic acid group. As the fluorotelomer olefins are dominated by F(CF2)8CH=CH2,[2][4] PFNA is the major PFCA product. Surflon S-111 "is described as Fatty acids, C7-C13, perfluoro, ammonium salts".[2] See also
