Perfluoroalkanesulfonylimides and their lithium salts: synthesis and characterisation of intermediates and target compounds

“…Excellent reviews have summarized the details of the Simons ECF process [1][2][3][4]. In particular, the ECF obtainment of perfluoroalkanesulfonylfluorides has been intensively investigated [5][6][7][8][9]12], with some contributions by Fluorine Chemistry Laboratory of Padua University [10,11].…”

Energy and Resource Efficient Production of Fluoroalkenes in High Temperature Microreactors

“…Therefore, an additional process step is necessary. Aschauer et al [14] showed that high yields of TFE could be obtained in a microwave plasma, when the feed consists of perfluorinated alkanes like C 2 F 6 and C 4 F 10 , which originated from ECF, as described by Schmeiser et al or Nagase et al (Table 2) [15,16].…”

“…The problem of utilizing feed gases from ECF is the low selectivity to perfluorinated products obtained in this process. Depending on the hydrocarbon used as feed in the ECF, up to 70% of the product spectrum consists of only partly fluorinated alkanes (Table 2) [15]. Production of 1000 t perfluorinated compounds results in waste streams of about 400 t of partly fluorinated residues.…”

Elimination of Perfluorinated Surfactants – Adsorbent Evaluation Applying Surface Tension Measurements

“…Perfluorinated surfactants have been produced in industrial scale for more than 60 years 1, 2 and were used since then in various applications ranging from consumer goods to plating solutions 3. But recently, these substances have drawn considerable attention due to several reports about their world‐wide distribution 4, 5, environmental persistence, and bioaccumulation potential 6.…”
