| 摘要 |
The present invention relates to a process for preparing (hydro)(chloro)fluoroolefins, comprising at least one step of liquid-phase fluorination of a (hydro)haloalkane or of a (hydro)haloalkene in the presence of at least one ionic liquid as catalyst. The ionic liquids are derived from Lewis acids based on aluminium, titanium, niobium, tantalum, tin, antimony, nickel, zinc or iron. |
