Catalytic fluorination of 1,1,1-trifluoro-2-chloro-ethane in the presence of oxygen over chromium based catalyst doped or not by zinc supported over partially fluorinated alumina

► Several reactions in competition for the transformation of the 1,1,1-trifluoro-2-chloro-ethane. ► Fluorination favored in the presence of small amount of zinc to chromium based catalyst. ► Same actives sites for the fluorination reaction and Deacon reaction.
