摘要
用长光路FTIR技术模拟研究氟里昂替代物HCFC22(CHCIF_2)在对流层中的光化学反应,氯原子作反应的引发剂.HCFC22在对流层中的主要含氟光解产物为COF_2.讨论了有关反应机理,并对HCFC22的环境影响和工业应用前景进行了评价.
HCFC22 (CHClF2) has been proposed as a substitute for the fully halogenated chlo-rofluorocarbon CFC12. This paper reports laboratory studies on photochemical reactions of HCFC22 in the troposphere, using long path Fourier transform infrared absorption spectroscopy and initiated by chlorine atoms. The main fluorine-contained product of HCFC22 during tropospheric degradation is COF2, which will be further transformed into CO2 and HF, and the reaction mechanism is discussed. The environmental effect and industry use prospect of HCFC22 are assessed.
