HALOGENATION PROCESS OF 1,1-DIHALOETHENE

The present invention concerns a halogenation process, in which a 1,1- dihaloethene CX2=CH2 (I) with at least one halogenation agent. The invention concerns further a process for the manufacture of chlorodifluoroacetic acid chloride (CDFAC), which comprise the steps of (a) chlorination of VF2, and (b) an oxidation process. Another object of the present invention is a process for the manufacture of agriculturally or pharmaceutically active compounds, comprising the halogenation and/or oxidation process.

PROCESS FOR PRODUCING PENTAFLUOROETHANE

The present invention relates to a process for producing pentafluoroethane. More particularly, the subject of the invention is a continuous process for producing pentafluoroethane comprising (i) a step of fluorinating perchloroethylene (PER) with hydrofluoric acid, in the gas phase, in the presence of a catalyst, (ii) a step of separating the products issuing from step (i) in order to give a fraction of light products and a fraction of heavy products, comprising hydrofluoric acid, unreacted perchloroethylene and under-fluorinated products, and (iii) a step of pretreating the fraction of heavy products before recycling to step (i).
