FLUORINATION CATALYST, METHOD FOR ITS PREPARATION AND METHOD FOR PRODUCING FLUORINATED COMPOUND USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a novel fluorination catalyst that has high stability at high temperatures, is easily regenerated and is superior in catalytic activity and selectivity and a method for the preparation of the fluorination catalyst and to provide a method for the preparation of a new fluorinated compound, and particularly, 1,1,1,3,3-pentafluoropropane (HFC-245fa), by using the catalyst.

SOLUTION: The fluorination catalyst is obtained by treating a metal salt containing a chromium salt such as chromium oxide with chlorine gas and/or oxygen gas. The metal salt can 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.
