A method for producing a composition containing at least one fluorine-containing olefin selected from 1,2-dichloro-3,3,3-trifluoropropene (HCFO-1223xd) and 1,1,2-trichloro-3,3, 3-trifluoropropene (CFO-1213xa), which comprises submitting at least one starting compound selected from the formulas CF3CHXCHX2 (1-1) and CF3CX=CX2 (1-2), wherein X is independently H or Cl, with the proviso that at least one X is Cl, to a gas phase oxychlorination reaction in a temperature range of <= 380°C in the presence of oxygen gas and HCl gas. |
