1. A method for producing a fluorine-containing olefin represented by Formula (7): CF3CA=CHB, wherein one of A or B is F, and the other is H,
the method comprising reacting anhydrous hydrogen fluoride with at least one chlorine-containing compound in the presence of a chromium atom-containing fluorination catalyst, the at least one chlorine-containing compound being selected from the group consisting of a chlorine-containing alkane represented by Formula (1): CX3CClYCH2Z, wherein X is independently F or Cl, Y is H or F, when Y is H, Z is Cl or F, and when Y is F, Z is H; a chlorine-containing alkane represented by Formula (2): CX3CH2CHX2, wherein X is independently F or Cl, and at least one X is Cl; a chlorine-containing alkene represented by Formula (3): CX3CCl═CH2, wherein X is independently F or Cl; a chlorine-containing alkene represented by Formula (4): CX3CH═CHX, wherein X is independently F or Cl, and at least one X is Cl; a chlorine-containing alkene represented by Formula (5): CH2XCCl═CX2, wherein X is independently F or Cl; and a chlorine-containing alkene represented by Formula (6): CHX2CH═CX2, wherein X is independently F or Cl, and at least one X is Cl; the reaction being carried out at a temperature within a range of 200 to 350° C. in the presence of 0.0001 to 0.03 mol of molecular chlorine per mol of the chlorine-containing compound. |
