HCID 8925TetraglymeSolvent

Procedure

36.2 g (0.08 mol) of CF3CFHOCF2CF(CF3)OCF2CF2CO2Na and 80 mL of tetraglyme were stirred and heated in a 200 mL 3-neck flask fitted with a thermometer, stirrer and distillation column topped by a Dry Ice-cooled trap and nitrogen bubbler. The salt largely dissolved and reaction was noted in the temperature range 180° to 195°. 17.9 g of colorless distillate was obtained. Gas chromatography and IR analysis confirmed the presence of ##STR1## (6.0 g, 28% yield), that is, the compound of formula 2 wherein X is F, X1 is H and n is 1, and CF3CFHOCF2CF(CF3)OCF2CF2H (9.5 g, 31% yield).
