Reaction Conditions:
with ammonia;water at 160 - 165; for 12 h;Autoclave;Reagent/catalyst;
Steps:
1
PPVE-2 (42.3 g, 0.1 mol) and a solution of ammonia/water (89.5 g of a 28-30 % solution, 0.74 mol) were added to a steel autoclave (300 mL) equipped with a stir bar. The reaction mixture was heated upon intensive mixing at 160 to 165 °C for 12 h. After cooling to room temperature, the gaseous products were removed. The liquid residue of the autoclave (bottom layer) was separated and washed with water (3 x 25 mL) to neutral pH, dried over Na2S04, and consisted of practically pure C3F7-O-CFH-CF3. The yield of C3F7-O-CFH-CF3 (molecular weight 286.0 g/mol) was 50 % (15.3 g, 0.05 mol), confirmed by NMR.
