Abstract
Hydrofluoric acid can be obtained, in addition to CO and/or CO2, from organic fluorine compounds which contain no halogens other than fluorine, at elevated temperature in the gas phase. To this end, the organic fluorine compound is admixed with enough water to permit (taking into account the hydrogen which may be bound) all the bound fluorine to be converted into HF, and at least enough oxygen to permit (taking into account the amount of oxygen which may be bound) the hydrogen not bound as HF to be converted into H2O and all of the bound carbon to be converted into CO and/or CO2. The mixture is heated to temperatures at which HF is formed, followed by separation of the generated hydrofluoric acid from the resulting gas mixture.
