Method for producing heptafluoropentane

摘要

The invention relates to a method for producing 1,1,2,2,3,3,4-heptafluorocyclopentane. This method includes the step of reducing 1,1-dichlorooctafluorocyclopentane by hydrogen in the presence of a hydrogenation catalyst. This catalyst contains at least one first metal selected from metals of 8, 9, and 10 groups of periodic table, such as iron, cobalt, palladium, platinum, rhodium, ruthenium, iridium, and osmium. According to this method, it is possible to produce 1,1,2,2,3,3,4-heptafluorocyclopentane with high yield and high selectivity.
