Reaction Steps
A 500 ml PFA vessel equipped with a stirrer was used. Water (250 g, 13.9 mol) was temperature conditioned to 15° C. within the vessel, following which C7F15COF (125 g, 0.3 mol) having a purity of 99.9 wt % was added dropwise under stirring. The resulting mixture was a solid-liquid dispersed system composed of an aqueous phase containing the hydrogen fluoride that formed in hydrolysis, and a solid phase of the C7F15COOH that formed in hydrolysis.
