Zusammenfassung:The present invention provides a process for producing 2,3,3,3-tetrafluoropropene, comprising the steps of producing 2-chloro-3,3,3-trifluoropropene by reacting anhydrous hydrogen fluoride with a specific chlorine-containing compound in a gas phase in the presence of a fluorination catalyst while heating; and producing 2,3,3,3-tetrafluoropropene by reacting 2-chloro-3,3,3-trifluoropropene with anhydrous hydrogen fluoride in a gas phase in the presence of a fluorination catalyst while heating, the step of producing 2-chloro-3,3,3-trifluoropropene being performed after the step of producing 2,3,3,3-tetrafluoropropene. According to the process, 2,3,3,3-tetrafluoropropene can be produced with reduced energy and equipment costs in an economically advantageous manner.
