Abstract:
The invention relates to a method for producing 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) from at least one compound A selected from the group consisting of halopropane of formulae CX 3 CHClCH 2 X or CX 3 CFClCH 3 , or halopropenes of formula CQX 2 CCNCH 2  and CX 2 ═CClCH 2 X 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 AlF 3  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).

Claim (Index 19):
The process as claimed in  claim 11 , wherein stream B also comprises 2,3,3,3-tetrachloropropene (HCO-1230xf), 1,1,2,3 -tetrachloropropene (HCO-1230xa), 1,1,1,2,3 -pentachloropropane (HCC-240db), 1,1,2,3 -tetrachloro-1-fluoropropane (HCFC-241db), 1,2,3-trichloro-1,1-difluoropropane (HCFC-242dc) or mixtures thereof.
