Original Fluorinated Surfactants Potentially Non- Bioaccumulable

摘要: Abstract This minireview updates non-exhaustive recent strategies of synthesis original fluorosurfactants potentially non-bioaccumulable. Various have been focused on (i) the preparation CF3–X–(CH2)n–SO3Na (with X = O, C6H4O or N(CF3) and n = 8–12), (ii) oligomerization hexafluoropropylene oxide (HFPO) to further synthesize oligo(HFPO)–CF(CF3)CO–RH (where RH stands for an hydrophilic chain); (iii) telomerization vinylidene fluoride (VDF) with 1-iodopentafluoroethane 1-iodononafluorobutane produce CnF2n+1–(VDF)2–CH2CO2R (n = 2 4, R = H NH4), (iv) radical 3,3,3-trifluoropropene (TFP) isoperfluoropropyliodide diethyl hydrogenophosphonate prepare (CF3)2CF(TFP)x–RH CF3–CH2–CH2–(TFP)y–P(O)(OH)2, (v) cotelomerization VDF TFP, their controlled copolymerization in presence (CF3)2CFI a fluorinated xanthate. In most cases, surface tensions versus surfactant concentrations assessed. These above led various highly (but yet not perfluorinated) telomers whose chemical changes enabled obtain surfactants as novel alternatives perfluorooctanoic acid (PFOA), ammonium perfluorooctanoate (APFO), perfluorooctylsulfonic (PFOS) regarded bioaccumulable, persistent, toxic.
