Abstract:
The invention relates to a process for producing 2,3,3,3-tetrafluoropropene performed using a starting composition, comprising the steps of placing the starting composition in contact with HF, in the presence of a catalyst, to produce a composition A comprising 2,3,3,3-tetrafluoropropene (1234yf), intermediate products B consisting of 2-chloro-3,3,3-trifluoropropene (1233xf), 1,1,1,2,2-pentafluoropropane (245cb), and side products C consisting of E-1-chloro-3,3,3-trifluoro-1-propene (1233zdE), trans-1,3,3,3-tetrafluoro-1-propene (1234zeE) and 1,1,1,3,3-pentafluoropropane (245fa); recovery of said composition A and purification thereof to form and recover a first stream comprising 2,3,3,3-tetrafluoropropene (1234yf) and one or more streams comprising 2-chloro-3,3,3-trifluoropropene (1233xf) and/or 1,1,1,2,2-pentafluoropropane (245cb); recycling into step a) of said one or more streams comprising 2-chloro-3,3,3-trifluoropropene (1233xf) and/or 1,1,1,2,2-pentafluoropropane (245cb).

Claim (Index 30):
The process as claimed in  claim 29 , wherein the stream L1f comprising 2-chloro-3,3,3-trifluoro-1-propene (1233xf) is recycled into step a).
