Retracted Article: Design, synthesis, and evaluation of a highly effective and safe perfluoro-alternative with a “weak site”: potassium 1,1,2,2,3,3,4,4-octafluoro-4-(perfluorobutoxy)butane-1-sulfonate

A novel, highly efficient, degradable alternative perfluorinated compound (APFC) with a “weak site” was synthesized using various methods via a common intermediate. The main reactions were oxidation by sulfonyl chloride, chlorination, and electrolytic fluorination. The synthetic strategies were efficient and suitable for industrial production of the APFC at the kilogram scale. The surface tension of the APFC and inhibition of chromium mist by the APFC were assessed. The APFC met the requirements for being produced industrially and also performed excellently, was resistant to degradation, and was shown to be more environmentally friendly than perfluorooctylsulfonic acid.
