| Abstract: | Under simulated atmospheric condition, photoomdation for HCFC-22 H2O2, HCFC-22 H2O2 O2, HFC-134A H2O2 and HFC-134A H2O2 O2 systems were studied.H2O2 was irradiated by low pressure mercury lamp and produced OH radicals. The OH radicals can initiate photooxidation of HCFC-22 and 134A. The products of photooxidation were determined by a Fourier Transform infrared Spectroscopy with a 20ml long path cell. The products were COF2,CO2, HCI, H2O and HF for HCFC-22 H2O2 system, HO, CO2, HCI and HF for HCFC-22 H2O2 O2 system, HCOF, CF3OOCF3,CO2, H2O and HF for HFC-134A H2O2 system, HCOF, CO2, H2O, and HF for HFC-134A H2O2 O2 system. Based on those results, the mechanisms of photooxidation were suggested. |
