Abstract
The present invention provides a process for preparing 2,3,3,3-tetrafluoropropene, comprising the following steps: (a) catalytic reaction of 1,1,1,2,3-pentachloropropane and/or 1,1,2,2,3-pentachloropropane with HF into product 2-chloro-3,3,3-trifluoropropene; (b) catalytic reaction of the thus-obtained 2-chloro-3,3,3-trifluoropropene into 2,3,3,3-tetrafluoropropene.
