Paragraph 0115; 0130-0131, (2020/11/27)
Provided are: a method of removing 2-chloro-1,3,3,3-tetrafluoropropene (1224xe), the method including bringing a mixture containing 1224xe and 1224yd into contact with an alkali optionally in the presence of a phase transfer catalyst; and a method of producing 1-chloro-2,3,3,3-tetrafluoropropene (1224yd), the method including bringing a mixture containing 1224xe and 1224yd into contact with an alkali optionally in the presence of a phase transfer catalyst.

Paragraph 0053-0054, (2017/03/24)
PROBLEM TO BE SOLVED: To provide a production method that suppresses the production of by-product and selectively produces 2-chloro-1,3,3,3-tetrafluoropropene(1224). SOLUTION: The method for producing 2-chloro-1,3,3,3-tetrafluoropropene(1224) comprises bringing an organic base into contact with 2,3-dichloro-1,1,1,3-tetrafluoropropane(234da). The organic base is preferably an organic base having a pKa of 7 or higher and more preferably, is an organic base having a pKa of 10 or higher. The organic base is preferably recovered and reused.

Method for Producing 2-Chloro-1,3,3,3-Tetrafluoropropene
-
Paragraph 0065, (2016/02/16)
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.
