Abstract (sommario):

Suite à la détection de quantités importantes de composés perfluorés dans des prélèvements d’air, de sol, d’eau ainsi que de lait maternel, deux arrêtés préfectoraux de la préfecture du Rhône, datant de mai 2022, ont défini les limites de quantification de ces contaminants environnementaux à 10 ng/L dans les eaux usées. Ces composés très persistants et considérés comme des perturbateurs endocriniens peuvent avoir des effets non négligeables sur la santé humaine. La nécessité de développer de nouveaux outils de détection et de quantification de ces molécules dans les eaux de rejets est donc urg

Abstract (sommario):

When perfluorinated 1-methyl- and 1-ethylbenzocyclobutenes, 2-methyl- and 2-ethylbenzocyclobutenones react with 20% oleum at 150°C, 3-perfluoroalkyl-4,5,6,7-tetrafluorophthalides and perfluoro-3hydroxy-3-alkylphthalides are formed in approximately equal proportions. Along with them, perfluoro-2hydroxy-2-methylbenzocyclobutenone was obtained in the reaction of perfluoro-2-methylbenzocyclobutenone with oleum at 100°C. Under the action of oleum, perfluoro-2-phenylbenzocyclobutenone forms perfluoro-2-benzoylbenzoic acid, and polyfluorobenzocyclobutene-1,2-diols form their cyclic sulfates.

Abstract (sommario):

Perfluorinated chemicals (PFCs) can be absorbed on fine particulate matter (PM2.5) and used as stain, water and grease repellent in a wide range of consumer products. Among the PFCs, perfluorooctane sulfonate (PFOS) and perfluoro octanoic acid (PFOA) are widely detected in human blood and serum and are of concern due to their potential toxicity. In the present experiment, fine particulate matter (PM2.5) from some northern (Beijing, Xian) and southern (Hong Kong, Guangzhou and Xiamen) cities of China were collected and analyzed for perfluoro butanoic acid (PFBA), perfluoro hexanoic acid (PFHxA)

Perfluorinated tetrathiacalix[4]arene was obtained by heating perfluoro-m-xylene with thiourea or 2,5-difluoro-4,6-bis(trifluoromethyl)benzene-1,3-dithiol at 90 °C. Interaction of perfluoro-m-xylene with resorcinol or orcinol under mild conditions and subsequent heating of the mixture with 2,5-difluoro-4,6-bis(trifluoromethyl)benzene-1,3-dithiol leads to polyfluorinated dioxadithiacalix[4]arenes.

The yield of ω–fluorosulfonyl perfluoroalkylation decreases with increase in the reactant molar ratio. The modified polymer was characterised by various techniques: the ring perfluoro{-1-[2-(2-fluorosulfonyl)propoxy]}ethylation was proved by FT-IR, 19F NMR and DSC; desulfonylation of the fluorinated polystyrene appe

Perfluoro epoxy compounds are important intermediates in organic chemistry, however, the methods for preparing them are scanty.

Catalytic epoxidation methods were developed by coupling this reaction with the N-oxidation of tertiary amine by hydrogen peroxide or MCPBA.

Abstract (sommario):

Novel per- and polyfluoroalkyl substances (PFAS) were recently identified in drinking water sources throughout North Carolina. These include the perfluoroether acids (PFEAs) perfluoro-2-methoxyacetic acid (PFMOAA), perfluoro-2-methoxypropanoic acid (PFMOPrA), and perfluoro-4-methoxybutanioc acid (PFMOBA). Little toxicological data exist for these PFEAs. Therefore, the present study described signs of toxicity and immunotoxicity following oral exposure. Adult male and female C57BL/6 mice were exposed once/day for 30 days to PFMOAA (0, 0.00025, 0.025, or 2.5 mg/kg), PFMOPrA, or PFMOBA (0, 0.5, 5

Eighteen per-and polyfluoroalkyl substances (PFASs) were investigated in surface waters of four river basins in Portugal (Ave, Leça, Antuã, and Cértima) during the dry and wet seasons. All sampling sites showed contamination in at least one of the seasons. In the dry season, perfluorooctanoate acid (PFOA) and perfluoro-octane sulfonate (PFOS), were the most frequent PFASs, while during the wet season these were PFOA and perfluobutane-sulfonic acid (PFBS). Compounds detected at higher concentrations were PFOS (22.6 ng L−1) and perfluoro-butanoic acid (PFBA) (22.6 ng L−1) in the dry and wet seas

Abstract (sommario):

Purpose. Analysis of electron microscopic changes in rabbit eyes with intravitreal tamponade of perfluorocarbon liquids (PFCL) (perfluoro-1,3-dimethylcyclohexane and perfluorodecalin).Material and Methods. The study was performed on Chinchilla breed rabbits. 25G vitrectomy with PFCL intravitreal tamponade was performed on 12 eyes of 6 rabbits (perfluorodecalin (Bausch+Lomb «Dk-line», USA) and perfluoro-1,3-dimethylcyclohexane (ZAO “Optimedservis”, Russia). Standard three-port vitrectomy technique was used. After removal of the vitreous body 2.5 ml of PFCL were injected in vitreous cavity. Rese

Abstract (sommario):

Absolute oscillator strength spectra in the C 1s (280–340 eV) and F 1s (680–740 eV) regions of the perfluoro-n-alkanes from C2 to C6 and perfluorocycloalkanes from C3 to C6 have been determined from inner-shell electron energy loss spectra recorded under electric-dipole scattering conditions. The spectral features are interpreted in terms of spatially localized transitions terminating at orbitals of predominantly σ*(C—F) and σ*(C—C) character. When compared to the spectra of the perfluoro-n-alkanes, both the C 1s and F 1s spectra of the perfluorocycloalkanes exhibit additional low-lying bands

Abstract (sommario):

Perfluoro-1-butanesulfonic acid (PFBS) was used to etch on the surface of a zinc anode to introduce a 3D C4F9O3S–Zn interface layer with unique fluorine groups (Zn@PFBS) to inhibit the formation of dendrites.
