| 摘 要： | 模拟大气条件研究了ＨＣＦＣ－２２＋Ｈ２Ｏ２在有氧或无氧存在下用低压相进行辐照，在２０ｍ的长光程池中用富里叶红外光仪测量其化学产物，结果表明在没有氧情况下产物为ＣＯＦ２，ＣＯ２，ＨＦ和ＨＣｌ；有氧存在时产物为ＣＯ２，Ｈ２Ｏ，ＨＦ和ＨＣｌ。从这些产物推广其可能的光解机理。

| Abstract: | Under simulated atmospheric condition, the HCFC-22+H2O2 in the presence or absence ofoxygen was irradiated by low pressure mercury lamp and the products of photolysis were determined by a Fourier Transform Infrured Spectroscopy with a 20 m long path cell.The products are COF2,CO2,HF and HCl for HCFC-22+H2O2 system,CO2,H2O,HF and HCl forHCFC-22+H2O2+O2 system. Based on these results, the mechanisms of photolysis were suggested. |
