MANUFACTURING METHOD OF COMPOSITION CONTAINING 1,2-DICHLORO-3,3,3-TRIFLUOROPROPENE (HCFO-1223xd) AND/OR 1,1,2-TRICHLORO-3,3,3-TRIFLUOROPROPENE (CFO-1213xa)

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a composition containing 1223xd and/or 1213xa in a vapor phase reaction with higher producibility than conventional ones.SOLUTION: There is provided a method for manufacturing a composition containing at least one kind of fluorine-containing olefin of 1,2-dichloro-3,3,3-trifluoropropene (HCFO-1223xd) and 1,1,2-trichloro-3,3,3-trifluoropropene (CFO-1213xa) by a vapor phase oxychlorination reaction of at least one kind of raw material compound of chlorine-containing alkane represented by the general formula (1-1): CFCHXCHX, where X is each independently H or Cl but at least one of X is Cl, and chlorine-containing alkene represented by the general formula (1-2): CFCX=CX, where X is each independently H or Cl but at least one of X is Cl, in a temperature range of 380°C or less in a presence of acidic gas and hydrogen chloride gas.
