| 中文摘要 |
| 模拟大气条件研究了HCFC-22+H2O2在有氧或无氧存在下用低压汞灯进行辐照,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.从这些产物推出其可能的光解机理。 |
| 英文摘要 |
| 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. |
