Tetrafluoroethane-1,1,1,2 AKA R134A is often easier to obtain than Freon 12 as being chlorine and bromine free it often escapes regulation, has
been used similarly
Quote: | The principle reaction involved is the transformation of BaO into fluorinated form. We have found that 1,1,1,2 tetrafluoroethane (CH2FCF3), a
refrigerant (R-134a) used in modern automotive air conditioning systems, serves perfectly as a source of fluorine. The precursor films were
fluorinated in a tubular furnace in a partial vacuum in an atmosphere of 4 Torr of CH2FCF3 and 200milli-Torr of oxygen, at a temperature of 600 .

True, they were preparing oxyfluorides but it still might prove useful. |
