Patent ID: 8318991

Claim:
A method for producing a hydrogen-containing fluoroolefin compound, comprising: bringing a fluorine-containing halogen compound into contact with 0.1 to 3 molar equivalents of hydrogen relative to the fluorine-containing halogen compound in a vapor phase in the presence of a supported palladium catalyst in which an amount of supported palladium is 0.1% by weight to 2.5% by weight; wherein the supported palladium catalyst is a catalyst in which a weight ratio between palladium and bismuth (Bi/Pd) falls within a range of 0.4 to 0.8 and which has been prepared by subjection to a hydrogen reduction treatment at a temperature in a range of 250° C. to 350° C.; said fluorine-containing halogen compound being represented by the formula (1): wherein n is 2, and X represents a chlorine atom, a bromine atom, or an iodine atom; said hydrogen-containing fluoroolefin compound being represented by the formula (2): wherein n is 2.
