FIG. 1 depicts the UV absorption spectrum chart at 220 nm to 400 nm of the Algin-EDA-Gly of Example 8 in an aqueous 0.05M NaHCO3 solution, analyzed by a Beckman spectrometer Type DU-65 using a photo-cell of a 1-cm optical path for measuring absorbance; FIG. 2 depicts the UV abso...
Each perfluoroalkanesulfonyl fluoride thus produced has a low boiling point of, for example, −21° C. (n=1), 0° C. (n=2), and 40° C. (n=3), and thus is discharged as gas from the electrochemical fluorination cell to the outside along with hydrogen generated as a byproduct,...
