Perfluorobutanesulfonyl fluoride

Assay:95%min.(GC) Appearance: clear colorless or slightly yellow liquid Boiling point: 65-66℃ Refractive index(n25D): 1.2810 Density (d420): 1.750-1.700 Assay: 95% min. ( GC ) PH: 3.8-4.8 Physical properties: Insoluble in water, it can hydrolyze in alkali to produce nonafluorobutanesulfo salt, then acidize to obtain nonafluorobutanesulfonic acid. Production method: HF C4F9SO2Cl --------- > C4F9SO2F Application: its properties is similar to perfluorooctanesulfonyl fluoride, it can be used to synthesize multi-kind of fluoro surfactant, its Potassium salt C4F9SO2K is a very good anion surfactant, also a best fire retardant for polycarbonate. Package: 50Liter or 200Liter / iron drum, inner lined with plastic coating N.W.: 70KG ( 50ltr) / 250KG ( 200ltr)
