FC-4 Perfluorobutanesulfonyl fluoride
Structure formula: CF3CF2 CF2CFSO2F
Molecular formula: n- C4F9SO2F
Molecular Structure:
CAS No. 375-72-4
Appearance: clear colorless or slightly yellow liquid
Refractive index(n25D): 1.2810
Density (d420): 1.750-1.700
Assay: 95% ( Chromatographic analysis)
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.
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.
