It is commonly used as a polymerization aid in the production of fluoropolymers. 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%).〔 (Supporting Information ) (PDF).〕 Surflon S-111 is synthesized in Japan by oxidizing a mixture of fluorotelomer olefins.〔 Fluorotelomer olefins are synthesized using a telomerization of tetrafluoroethylene taxogens (monomers),〔 followed by an ethylene insertion.〔 The olefin is oxidized, removing one carbon to yield products with an odd number of carbons〔 with even-lengthed fluorocarbon chains plus a carboxylic acid group. As the fluorotelomer olefins are dominated by F(CF2)8CH=CH2,〔 PFNA is the major PFCA product. Surflon S-111 "is described as Fatty acids, C7-C13, perfluoro, ammonium salts".〔 ==See also== *Fluorosurfactants 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Surflon S-111」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
