| 摘要 |
The invention consequently relates, in one aspect, to a process for obtaining a hydrofluoroalkane comprising at least two carbon atoms, which is purified of unsaturated organic impurities, according to which the hydrofluoroalkane containing organic impurities including (chloro)fluoro olefins is subjected to at least one purification treatment with bromine or BrCl, preferably in the presence of, an initiator. The process is suitable, for example, to purify 1,1,1,2-tetrafluoroethane. A further aspect concerns the application of LEDs or OLEDs to support chemical reactions of the gas-gas, liquid-liquid or gas-liquid type, and a respective reactor.
