Potassium nonafluoro-1-butanesulfonate Usage And Synthesis
Chemical Properties    White crystal
Purification Methods    Wash it with H2O and dry it in vacuo. When the K salt is distilled with 100% H2SO4, it gives the free acid which can be distilled (b 105o/22mm, 210-212o/760mm) and then converted to the pure K salt. [Gramstad & Haszeldine J Chem Soc 2640 1957, Beilstein 2 IV 818.]
