Production of hydrofluorocarbons |
| abstract |
A process for the production of a hydro(halo)fluorocarbon which comprises contacting an .alpha.-fluoroether in the vapour phase at an elevated temperature with a catalyst and wherein the catalyst is treated whereby to maintain and/or restore its activity. The catalyst treatment comprises either: (i) heating the catalyst to an elevated temperature above about 250°C in the absence of an .alpha.-fluoro ether, or (ii) contacting the catalyst at an elevated temperature with an oxidising agent whilst or between the times when the .alpha.-fluoro ether is contacted with the catalyst. The catalyst may be an oxidation promoting metal, for example zinc, iron or copper, carried on a metal oxide, fluoride or oxyfluoride support. |
