Abstract
Trifluorobromomethane is produced in a continuous process wherein chloroform is fluorinated with an excess of gaseous hydrogen fluoride and the trifluoromethane so formed is brominated, after the removal of hydrogen chloride and hydrogen fluoride therefrom, using an excess of bromine in a reaction vessel the walls of which have an inner surface consisting of a sintered oxide of a metal of Group II to IV of the Periodic Table. It is of advantage to use up to a 50% mole excess of hydrogen fluoride and of bromine with a fluorination temperature of at least 300 DEG C., preferably 420 DEG to 500 DEG C. and a bromination temperature of 650 DEG to 800 DEG C., preferably 700 DEG to 750 DEG C.Suitable oxides mentioned are aluminium, zirconium and magnesium oxides. An aluminium fluoride catalyst may be used in the fluorination process. Specification 770,640 is referred to.ALSO:Trifluoromethane is brominated in a reaction zone bounded by walls of which the inner surfaces consist of a sintered oxide of a metal of Group II to IV of the Periodic Table. The reaction zone may take the form of tubes, provided with external heating means, made from the sintered oxide, preferably aluminium oxide, and being connected together by metal couplings which are not heated and which consist of special steels or alloys thereof, or preferably consist of nickel. Other oxides mentioned are zirconium and magnesium oxides. Specification 770,640 is referred to.
