Abstract: Cpds. (I) of formula CF3(CF2)nSO2F (in which n is 2-14) are produced by electrolysing a mixt. of cpds. (II) of formula CH3(CH2)nSO2F and HF at 4-7.5 V, using 0.3-5 wt.% (II) w.r.t HF. (I) can be used as surfactants, solvents, textile ausiliaries, esp. for water- and oil-proofing, and as starting materials for lubricants, dielectrics and hydraulic fluids.
