Procedure
Then a reactor was charged with 12 g of the octafluorocyclopentene and 0.24 g of a 5%-palladium/carbon catalyst and hydrogenation was conducted at a temperature of 50° C. and a hydrogenation pressure of 6 kg/cm2. When the absorption of hydrogen ceased, the reaction was completed. After the removal of the catalyst and the produced hydrogen fluoride from the reaction mixture, the reaction mixture was distilled to give 9 g of 1,2,3,3,4,4,5,5-octafluorocyclopentane (b.p., 79° C.; purity, 99%).
