摘要：
A method for the preparation of a novel fluorinated compound, particularly 1,1,1,3,3-pentafluoropropane (HFC-245fa), by using a fluorination catalyst obtained by treating a metal salt containing a chromium salt such as chromium oxide with chlorine gas and/or oxygen gas. Examples of the metal salt may include, besides a chromium salt, one or more catalytically active metal salts selected from magnesium salts, aluminum salts, zinc salts, sodium salts, nickel salts, iron salts, cobalt salts, vanadium salts, manganese salts and copper salts.
