Process for preparing dichlorofluoroacetyl halides |
abstract |
Process for preparing dichlorofluoroacetylfluoride (CFCl 2 COF) comprising the following steps: n a) fluorination with hydrofluoric acid (HF) of the trichloroacetyl halide in a fixed or fluidized tubular bed reactor, filled with fluorination catalysts and having a temperature profile between the inlet of the reactants and the outlet of the reaction products, in the range from 175° C. to 275° C. n b) distillation of the reaction products with trichloroacetylfluoride recycle and recovery of a mixture formed by HF and CFCl 2 COF; n c) separation of the HF/CFCl 2 COF mixture components by cooling at temperatures lower than -10° C., and optionally the HF recycle. |
