A process for the preparation of 2,3,3,3-tetrafluoropentene (CF3CF=CH2), a process comprising the dehydrohalogenation of 1,1,1,2,2-pentafluoropropane (CH3CF2CF3) and/or 1,1,1,2 -tetrafluoro-2-chloropropane, in the presence of a base, the process further comprising the step of converting 1,1,1-trifluoro-2,3-dichloropropane (243db) into CH3CF2CF3 and/or 1,1,1,2- tetrafluoro-2-chloropropane, contacting 234db with HF in the presence of a catalyst. |
