根据国际协议，氯氟烃(CFCs)正在被环境可接受的替代品取代。氢氟烃(HFC)是一类氯氟化碳替代品。例如，HFC-134a是汽车空调系统中使用的CFC-12的替代品。在大规模工业使用之前，需要考虑氢氟碳化合物大气排放对环境的影响。CF3自由基是在HFC-23(1)、HFC-125(2-4)和HFC-134a(5，6)的氧化过程中产生的。在大气中，CF3自由基与O2反应生成CF3C>；2自由基，后者又迅速与NO反应生成
By international agreement, chlorofluorocarbons (CFCs) are being replaced with environmentally acceptable al-ternatives. Hydrofluorocarbons (HFCs) are one class of CFC substitute. For example, HFC-134a is a replacement for CFC-12 in automotive air conditioning systems. Prior to large-scale industrial use, the environmental impact of the atmospheric release of HFCs requires consideration. CF3 radicals are produced during the oxidation of HFC-23 (1), HFC-125 (2-4), and HFC-134a (5, 6). In the atmosphere, CF3 radicals react with O2 to give CF3C> 2 radicals which, in turn, react rapidly with NO to form
