Role of primary reaction initiated by 254 nm UV light in the degradation of p-nitrophenol attacked by hydroxyl radicals.
The degradation kinetics of p-nitrophenol (p-NP) exposed to 254/185 nm UV light were studied in two modes, i.e., 254 nm UV light intensity enhanced mode and normal mode. It was observed that the extra 254 nm UV light source accelerated the degradation process both in the presence and the absence of oxygen. Considering that hydroxyl radical (*OH) is the dominant factor that causes the degradation of p-NP, the enhanced degradation that occurred in the presence of the extra light source was attributed to the synergistic effect between *OH attack and the primary reactions initiated by 254 nm UV light. The synergistic effect has been confirmed by 266 nm laser flash photolysis (LFP) experiments. It is demonstrated that the phenoxy radical generated from the photoionization of p-NP is capable of reacting with *OH. On the basis of these results, it should be noted that UV light could cause more severe damage to p-NP attacked by *OH in aqueous solution.
Kinetic study of the thermolysis of anisole in a hydrogen atmosphere
The gas-phase thermal decomposition of anisole diluted in a 10-fold excess of hydrogen has been studied at atmospheric pressure in a tubular flow reactor over the temperature range 793-1020 K. In the overall process the unimolecular decomposition PhOCH 3 →PhO . +CH 3 . (1) plays a prominent role. The rate constant k 1 was separately determined between 790 and 875 K, employing a large (85-fold) excess of p-fluorotoluene as a carrier, and found to obey 10 15.3(±0.2) exp[(-63.6(±0.7) kcal mol -1 )/RT] (s -1 )
