Procedure

Conversion of CF3CF2CF2OCF(CF3)CF2OCF═CF2 to CF3CF2CF2OCF(CF3)CF2OCF2COOCH3 (bp 91-92° C. at 133 mbar) was carried described in U.S. Pat. No. 4,987,254. The ester was reacted with aqueous ammonia and methanol was removed by distillation resulting in CF3CF2CF2OCF(CF3)CF2OCF2COONH4. All structures were confirmed by F-NMR spectra. Due to an isomer content in the vinyl ether, an isomer with the structure CF3CF2CF2OCF2CF(CF3)OCF2COOX (X═CH3, NH4) was found.
