실험 절차
82.8 g of perfluorooctanoic acid (0.197 mol) are neutralized with a 20% aqueous KOH-solution to a pH of 6 and the salt mixture formed by octanoate and KF is dried for 24 hours at 100° C./1 mbar. Thereafter 70 ml of tetraglyme are added. After addition of 100 g of perfluoro-(3,6-dimethyl-1,4-dioxanyl-2-oxy)-propionic acid fluoride, the mixture is stirred for 15 hours and the product mixture is treated as in Example 1. By distillation there are obtained 102 g (62.2% of the theory, calculated on used perfluorooctanoic acid) of the compound of the formula ##STR12## having a boiling point of from 210° to 222° C., the structure of which is confirmed by the analysis and by spectroscopic data.
