Abstract: Disclosed in the present disclosure is a method for preparing 2,3,3,3-tetrafluoropropene. The method includes a two-step method for preparing 2,3,3,3-tetrafluoropropene, a method for co-producing 2,3,3,3-tetrafluoropropene and 1-chloro-2,3,3,3-tetrafluoropropene, and a method for co-producing 2,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene. The two-step method for preparing 2,3,3,3-tetrafluoropropene includes: A1, a telomerization step: subjecting chlorofluoromethane and trifluoroethylene to a pressure telomerization reaction under the action of a telomerization catalyst to prepare 3-chloro-1,1,1,2-tetrafluoropropane, wherein the telomerization catalyst is a Lewis acid catalyst or a mixed catalyst of a Lewis acid catalyst and dichloromethane; and A2, a dehydrochlorination step: subjecting the 3-chloro-1,1,1,2-tetrafluoropropane to dehydrochlorination under the catalytic action of activated carbon to obtain 2,3,3,3-tetrafluoropropene. The method for preparing 2,3,3,3-tetrafluoropropene has the advantages of a simple process, high product selectivity, mild reaction conditions and the like.
