Abstract
A manufacturing method for 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) wherein 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) is obtained by reacting hexafluoropropene (HFP) with anhydrous hydrogen fluoride (HF) under the presence of antimony catalyst. A manufacturing method can be provided in which HFC-227ea can be obtained at high yield under the mild condition without producing by-products such as olefin compounds and so on.
