Abstract (en)
[origin: WO2017129878A1] The invention relates to a method for producing 2-chloro-3,3,3-trifluoropropène (HCFO-1233xf) from at least one compound A selected from the group consisting of halopropane of formulae CX3CHCICH2X or CX3CFCICH3, or halopropenes of formula CQX2CCNCH2 and CX2=CCICH2X where X independently represents a fluorine or chlorine atom, characterised in that it comprises bringing said at least one compound A into contact with HF in a gaseous phase in the presence of a fluorination catalyst AIF3 or fluorine-bearing alumina in order to form a gaseous flow B comprising 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) et 3,3,3-trifluoropropene (HFO-1243zf).
