Φ-sulfo Fatty Methyl Ester Sulfonates (Φ-mes): A New Anionic Surfactant

AbstractF-Sulfo Fatty Methyl Esters  sulfonates (F- MES) are new anionic surfactants  obtained via sulfoxidation of fatty acid methyl esters (FAME) with SO2, O2, and ultraviolet light of appropriate wavelength.  The designation of  Φ refers to the random positioning of SO3 in the alkyl chain.In this work we summarize the most relevant results of our research started fifteen years ago, on  the synthesis, separation, analysis and performance of F-sulfo fatty methyl ester sulfonates known as  F-MES, and we update our last findings . We have to point out that we are f…
