Abstract
The object is to provide a process for producing highly pure 2,3,3,3-tetrafluoropropene, whereby formation of 3,3,3-trifluoropropene is suppressed.A process for producing 2,3,3,3-tetrafluoropropene, which comprises reacting a raw material compound composed of 1,1-dichloro-2,3,3,3-tetrafluoropropene and/or 1-chloro-2,3,3,3-tetrafluoropropene, and hydrogen in a gas phase in a reactor having a catalyst layer packed with a catalyst-supporting carrier, while maintaining the maximum temperature of the catalyst layer to be at most 130° C., to obtain formed gas containing 2,3,3,3-tetrafluoropropene, and then, contacting the formed gas discharged from the reactor, with alkali at a temperature of at most 100° C.
