Process for Preparing C3-6(Hydro)Fluoroalkenes by Dehydrohalogenating C3-6 Halo(Hydro)Fluoroalkanes in the Presence of a Zinc/Chromia Catalyst |
| 摘要 |
The invention relates to a process for preparing a C3-6 (hydro)fluoroalkene comprising dehydrohalogenating a C3-6 hydro(halo)fluoroalkane in the presence of a zinc/chromia catalyst, wherein the C3-6 (hydro)fluoroalkene produced is isomerised in the presence of the zinc/chromia catalyst. |

1. A process for preparing 2,3,3,3-tetrafluoropropene (CF3CF═CH2) comprising:
(i) fluorinating 3,3,3-trifluoro-2-chloropropene (CF3CCl═CH2) with HF to produce an intermediate composition comprising 1,1,1,2-tetrafluoro-2-chloropropane (CF3CFClCH3); and (ii) dehydrochlorinating the CF3CFClCH3 in the intermediate composition to produce CF3CF═CH2. |
