METHOD OF REMOVING 2-CHLORO-1,3,3,3-TETRAFLUOROPROPENE AND METHOD OF PRODUCING 1-CHLORO-2,3,3,3-TETRAFLUOROPROPENE

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.

METHOD OF PRODUCING HYDROCHLOROFLUOROOLEFIN AND METHOD OF PRODUCING 2,3,3,3-TETRAFLUOROPROPENE

There is provided an industrially advantageous and efficient method of producing a Z-isomer of HCFO-1224yd or HCFO-1223xd by isomerizing an E-isomer thereof. The method produces HCFO (Z-isomer) by causing specific HCFO (E-isomer) contained in a raw material composition to undergo an isomerization reaction under a condition where the HCFO (E-isomer) is isomerized.

Synthesis of > and Some Chlorofluoropropenes

The starting substances C3Cl5F3 (1) and C3Cl4F4 (2) prepared earlier by the addition of CCl3F with CClF=CClF and/or CF2=CClF were utilized for the synthesis of chlorofluoropropenes by means of fluorination, reduction of C-Cl bonds in halogenopropanes, and final dehalogenation, all the reactions being performed at atmospheric pressure.The reaction conditions permit laboratory scale production.The contents of the isomeric admixtures in the resultant products were determined by NMR spectroscopy.The starting halogenopropanes 1, 2 represent mixtures of isomers, but in course of the individual synthetic steps the content of the main isomer was generally increased.In comparison with previously used syntheses, our procedure proves advantageous for the synthesis of "perfluoroallylchloride" (9a, isomer purity 95percent).Using this procedure a number of halogenopropanes were prepared and dechlorinated to give the corresponding halogenopropenes (isomer purity percent): CClF2-CClF-CCl2F (2a, 87), CF3-CClF-CCl3 (2b, 78), CClF2-CClF-CClF2 (3a, 87), CF3-CClF-CCl2F (3b, 90), CF3-CClF-CHCl2 (5a, 90), CF3-CClF-CHClF (6a, 73), CClF2-CF=CClF (8a, 93), CF3-CF=CCl2 (8b, 84), 9a, CF3-CF=CClF (9b, 86) and CF3-CF=CHCl (11a, 84).The minor isomers in substance 2 yielded products which were isolated after being combined from several preparations: CClF2-CF2-CHCl2 (5b, 84); CClF2-CF=CHCl (10a, 98), which by addition of chlorine yielded CClF2-CClF-CHCl2 (4a, 95).The NMR spectra of all the major and minor products, excluding perhalogenopropanes, are listed.
