12--333-HCFO-1223xd / 112--333-CFO-1213xa PRODUCTION METHOD FOR COMPOSITION CONTAINING 12-DICHLORO-333-TRIFLUOROPROPENEHCFO-1223XD AND/OR 112-TRICHLORO-333-TRIFLUOROPROPENECFO-1213XA

摘要

The present invention provides a method for producing a composition containing 1223 x d and / or 1213 x a by a gas phase reaction, and a manufacturing method with higher production efficiency than the conventional method. The present invention relates to a chlorine-containing alkane represented by the general formula (1-1): CF ₃ CHXCHX ₂ (wherein X is each independently H or Cl, with the proviso that at least one of X is Cl) (1-2): at least one raw material compound among chlorine-containing alkenes represented by CF ₃ CX = CX ₂ (wherein X is each independently H or Cl, provided that at least one of X is Cl) Dichloro-3,3,3-trifluoropropene (HCFO-1223xd) and 1,1-dichloro-3,3,3-trifluoropropene (HCFO-1223xd) can be obtained by a gas phase oxychlorination reaction in the temperature range of 380 DEG C or less in the coexistence of an oxidizing gas and a hydrogen chloride gas. , And 2-trichloro-3,3,3-trifluoropropene (CFO-1213xa). The present invention also provides a method for producing a composition containing at least one fluorine-containing olefin.
