Potassium Bicarbonate → HCID 178526055, compound

Participants

Reaction Steps

Potassium hydrogen carbonate (6.03 g) was charged into a flask together with monoglyme (59 mL), and (FSO2CF2)2CFOCF2CF2CF2OCF(CF3)COF (35.6 g) obtained in Example 3 was added dropwise thereto with stirring under cooling with ice. Vacuum drying was carried out for 30 minutes and then vacuum drying was further carried out at 120° C. for 48 hours to obtain (FSO2CF2)2CFOCF2CF2CF2OCF(CF3)COOK (21.1 g). The obtained (FSO2CF2)2CFOCF2CF2CF2OCF(CF3)COOK was heated at 200° C. under 400 Pa (absolute pressure), and generated gas was collected in a trap cooled with liquid nitrogen to obtain a liquid (8.35 g). The liquid was analyzed by NMR and GC and as a result, formation of the title compound (NMR yield: 25%, GC purity: 87%) was confirmed. Further, as another component, formation of (FSO2CF2)2CFOCF2CF2CF2OCFHCF3 was confirmed.
