Procedure
A stainless steel reactor, the inner wall of which was lined with a fluoroplastic, was charged with 5.0 g of 1,2-dichlorohexafluorocyclopentene, 0.1 g of a 5%-palladium/carbon catalyst and 4.1 g of triethylamine, and hydrogen gas was introduced to a pressure of 5 kg/cm2. The mixture was heated to 40° C. while being stirred, and the reaction was conducted while the hyfrogen consumed was supplemented. After 7 hours' reaction, it was confirmed that the consumption of hydrogen ceased. Then the catalyst was removed from the reaction mixture and the reaction mixture was distilled to give 4.2 g of 1,1,2,2,3,3-hexafluorocyclopentane (b.p., 84.5-85° C. ).
