Reaction Conditions:

with hydrogen;Rh/C in water at 20 - 90; under 7500.75 Torr; for 18 h;

Steps:

2.15 g of 5 wt% Rh/C catalyst was introduced together with 32.8 g of water and 39.8 g of perfluoropropionic acid at room temperature into an autoclave reactor. The reactor was then purged with helium. H₂ was bubbled into the solution via a dipping tube at a flow-rate of 8 liter / h. The pressure was set to 10 bar and the reactor temperature was increased to 90°C. After 18 hours, the autoclave was cooled down to room temperature and vented. The collected liquid phase was filtered and then introduced into a decantation funnel. The lower phase containing the pentafluoropropanol was separated and distilled in the presence of anhydrous H₂SO₄ (30 wt%) to give pure pentafluoropropanol containing 50 ppm of water (quantitative yield measured by gas chromatography (GC)). The yield in pentafluoropropanol was 99 %.
