A production method of 2-chloro-1,3,3,3-tetrafluoropropene (1224) according to the present invention includes bringing 2,3-dichloro-1,1,1,3-tetrafluoropropane (234da) into contact with an inorganic base having a pKa of 4.8 or greater in an aqueous medium in the presence of a phase transfer catalyst. Preferably, the inorganic base has a pKa of 10 or greater. Further, the phase transfer catalyst is preferably at least one selected from the group consisting of tetrabutylammonium bromide, methyltri-n-octylammonium chloride, benzyltrimethylammonium chloride and tetraethylammonium chloride. It is possible by this method to selectively produce 1224 from 234da.

A method for producing 1234Z from 1234E while generation of 245fa as a byproduct is suppressed. The method for producing cis-1,3,3,3-tetrafluoropropene includes putting trans-1,3,3,3-tetrafluoropropene into contact with a catalyst. The trans-1,3,3,3-tetrafluoropropene is put into contact with the catalyst at a reaction temperature of higher than or equal to 200 C. and lower than or equal to 550 C. for a contact time of longer than or equal to 0.01 seconds and shorter than or equal to 500 seconds.
