| Abstract: | 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. |
