Oleum has some advantages over pure sulfur trioxide and may be successfully used for preparation of beta-sultones from hexafluoropropene, 2H-pentafluoropropene, 6H-perfluoro-1-hexene and perfluoro(propylvinyl) ether (VE). Depending on the reaction conditions, the VE-sultone and tetrafluoroethane-beta-sultone (TFE-sultone) are different from other sultones. They are not stable in the presence of oleum
与纯三氧化硫相比,油毡具有一些优势,并且可以成功地用于由六氟丙烯,2H-五氟丙烯,6H-全氟-1-己烯和全氟(丙基乙烯基)醚(VE)制备β-内酯。根据反应条件,VE-磺内酯和四氟乙烷-β-磺内酯(TFE-磺内酯)与其他磺内酯不同。它们在发烟硫酸存在下不稳定,磺内酯中的–CF 2 –SO 2-基团被氧化会生成一些新的氟代草酸酯衍生物。
