PROBLEM TO BE SOLVED: To provide a process of producing 2-chloro-3,3,3-trifluoropropene (HCFO 1233xf), which is expected to be an important candidate substance of compounds that have low ODP (ozone depletion potential) and low GWP (global warming potential) and do not affect the ozone layer.SOLUTION: A production process comprises gas-phase catalytic fluorination of 1,1,1,2,3- pentachloropropane (HCC 240db) or/and 1,1,2,2,3-pentachloropropane (HCC 240aa) into HCFO 1233xf in the presence of oxygen and a co-catalyst selected from Ni, Co, Zn, Mn and mixtures thereof and supported on fluorinated alumina, fluorinated chromia, fluorinated activated carbon or graphite carbon.SELECTED DRAWING: None |
