| 摘要 |
The present invention relates to a method for preparing fluorinated olefin compounds, in particular (chloro)fluoropropenes and (chloro)fluorobutenes, and specifically, the fluorinated compound 2,3,3,3-tetrafluoro-1-propene, including at least one step of fluorination, in the gaseous phase, with HF and at least one compound selected from the halopropenes having formula the CX3CHClCH2X and the halopropenes having the formulas CX3CC1═CH2, CClX2CCl═CH2 and CX2═CClCH2X, where X is, independently, a fluorine or chlorine atom, in the presence of oxygen and a fluorination catalyst suspended in a fluidized-bed reactor. |
