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.

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

The invention discloses a preparation method of E-1-halogen-3, 3, 3-trifluoropropene. The preparation method comprises the following steps: in the presence of a block catalyst, carrying out gas-phase fluorination reaction on 1, 1, 1, 3, 3-pentachloropropane and hydrogen fluoride in a tubular reactor to obtain a main product E-1-chlorine-3, 3, 3-trifluoropropene and a small amount of product Z-1-chlorine-3, 3, 3-trifluoropropene; furthermore, in the presence of the block catalyst, E-1-chlorine-3, 3, 3-trifluoropropene or/and Z-1-chlorine-3, 3, 3-trifluoropropene and hydrogen fluoride are subjected to a gas-phase fluorination reaction in the tubular reactor, and a main product E-1, 3, 3, 3-tetrafluoropropene is obtained. The one-way yield of the method is high; especially for the second-step process, only HCl in the product flow in the first step needs to be removed, and the remaining substances can be directly used for fluorination reaction after new HF is added. The block catalyst has the characteristics of high activity and long service life.
