Preparation method of E-1, 3, 3, 3-tetrafluoropropene

The invention discloses a preparation method of E-1, 3, 3, 3-tetrafluoropropene, which comprises the following steps: by taking 3, 3, 3-trifluoropropyne or/and an isomer 1, 3, 3-trifluoropropadiene thereof as a raw material, carrying out gas-phase selective fluorination reaction in the presence of a fluorination catalyst to obtain E-1, 3, 3, 3-tetrafluoropropene. The method provided by the invention is mainly used for producing E-1, 3, 3, 3-tetrafluoropropene in a high-efficiency and gas-phase continuous circulation manner.

Preparation method of Z-1-halogen-3, 3, 3-trifluoropropene

The invention discloses a preparation method of Z-1-halogen-3, 3, 3-trifluoropropene. The preparation method comprises the following steps: in the presence of a block catalyst, E-1-halogen-3, 3, 3-trifluoropropene is subjected to a gas phase isomerization reaction in a tubular reactor to obtain Z-1-halogen-3, 3, 3-trifluoropropene, and halogen is fluorine or chlorine. According to the preparation method, 1, 1, 1, 3, 3-pentachloropropane is used as an initial raw material, Z-1-chloro-3, 3, 3-trifluoropropene or Z-1, 3, 3, 3-tetrafluoropropene secondary product is prepared through a gas-phase fluorination reaction and an isomerization reaction, the materials which are not completely reacted are independently circulated through a gas-phase independent circulation process so that the initial raw materials can be almost completely converted into the target product, and finally, the target product is extracted from a process system, and thus liquid waste and waste gas are not generated, and green production is realized.
