C 8 H 17 SO 2 F + 17 F − → C 8 F 17 SO 2 F + 17 H + + 34 e −. This reaction results in a 25% yield for POSF, less than that for shorter perfluorosulfonyl fluorides. [2] The POSF obtained is impure as it is a mixture of linear and branched isomers, with ~70% linear. [2] POSF can also be obtained by ECF of the sulfonyl halide octanesulfonyl ...

Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS).
GitHub (/ ˈ ɡ ɪ t h ʌ b /) is a proprietary developer platform that allows developers to create, store, manage, and share their code.

Danielle R. Sassoon, the top federal prosecutor in Manhattan, has resigned days after being ordered by the Justice Department to drop corruption charges against mayor Eric Adams.
Many perfluorinated compounds have properties that are quite different from their C-H containing analogues. Common functional groups in PFCs are OH, CO 2 H, chlorine, O, and SO 3 H. Electrofluorination is the predominant method for PFC production. Due to their chemical stability, some of these perfluorinated compounds bioaccumulate.
