为了缩短引进全卤化氯氟碳化台物的替代物的时间进程,杜邦公司已经研究出一些环境上可以接受的由三种成份混合而成的化合物专利技术。这种技术目前仍在研究阶段,如果成功将使 CFCs 更迅速地从市场上被淘汰下来。杜邦公司已取得了这些混合工质的专利。这些混合工质将被证明是取代目前制冷和空调设备所用 In order to reduce the time-course for the introduction of alternatives to perhalogenated chlorofluorocarbons, DuPont has developed a number of environmentally acceptable compounds that are patented by three components. This technology is still at the research stage, and if successful, CFCs will be phased out more quickly from the market. DuPont has made these patented mixtures. These mixtures will prove to be replacing the current refrigeration and air conditioning equipment used
