| Abstract: | The photolysis of CH3OH/Cl2/air, CH3OH/Cl2/NO2/air, and (CH3)2CHOH/Cl2/NO2/air at 28 ± 2°C was studied using the long-path FTIR method. The primary reactions of methanol and isopropanol with Cl atoms were α-hydrogen abstraction (100%), and α hydrogen (85%), and α-hydrogen abstraction (15%), respectively. The failure to detect hydroxyalkyl-peroxy nitrates suggested that the oxygen addition to α-hydroxy radicals is not important. From the product distribution an upper limit of the ratio of oxygen addition to CH2OH and CH3CHOH was estimated to be about 6 and 7%, respectively. The oxygen addition ratio to (CH3)2COH was very low. The reaction mechanism is also discussed. |
