In the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf), formation of HFC-254eb as an excessively reduced product is suppressed. n A process for producing 2,3,3,3-tetrafluoropropene, which comprises reacting a raw material compound gas composed of at least one of 1,1-dichloro-2,3,3,3-tetrafluoropropene and 1-chloro-2,3,3,3-tetrafluoropropene, and hydrogen gas, in the presence of a catalyst, wherein the catalyst is a catalyst having palladium supported on active carbon, and the ratio of the number of moles of the hydrogen gas to the number of moles of chlorine atoms in the raw material compound gas (H 2 /Cl) is at most 0.7. |
