Abstract
The object is to provide a process for producing highly pure 2,3,3,3-tetrafluoropropene, whereby formation of 3,3,3-trifluoropropene as a by-product is suppressed.A process for producing 2,3,3,3-tetrafluoropropene, which comprises introducing and reacting a raw material compound composed of at least one of 1,1-dichloro-2,3,3,3-tetrafluoropropene and 1-chloro-2,3,3,3-tetrafluoropropene, and hydrogen, in a catalyst layer packed with a catalyst-supporting carrier, wherein the temperature of the catalyst layer is controlled to be higher than the dew point of the raw material mixed gas comprising the raw material compound and the hydrogen, and the maximum temperature of the catalyst layer is maintained to be at most 130° C. during the reaction.
