Witryna19 lis 2024 · We started the polymerization of (S)-1,1′-binaphthyl-2,2′-diol with a stoichiometric amount of 4,4′-difluoro benzophenone or 4,4′-difluorophenylsulfone in the presence of K 2 CO 3 in DMAc at 160 °C. The produced water was removed before polymerization by azeotropic distillation with toluene. WitrynaOf the 13 emerging PFAS, Nafion byproduct-2 (Nafion BP2), Hydro-EVE, PFO 4 DA, and PFO 5 DoA had the largest increases in percent composition when comparing serum and liver to the dosing solution, suggesting that these PFAS may have the highest bioaccumulation potential. This finding supports other studies that detected …
