在 6400-1 室内全聚四氟乙烯室中研究了在 NO 存在下由 OH 自由基引发的菲气相反应。通过高效液相色谱分馏和气相色谱/质谱分析鉴定反应产物。鉴定出的反应产物为芴酮、2,2'-二甲酰联苯、1,4-和9,10-蒽醌、9,10-菲醌、6H-二苯并[b,d]吡喃-6-酮、三种菲酚异构体、联苯酸酐、1-、2-、3-、4-和9-硝基菲，以及2-和4-硝基-6H-二苯并[b,d]吡喃-6-酮。其他五种含氧产品只能暂时通过其分子式来表征。将鉴定出的化合物与在模拟环境条件下用其他氧化剂观察到的菲降解产物进行比较。讨论了环境大气样品中已识别化合物的出现情况。
The OH radical-initiated gas-phase reaction of phenanthrene in the presence of NO, was investigated in a 6400-1 indoor all-Teflon chamber. Reaction products were identified by high-performance liquid chromatography fractionation and gas chromatography/mass spectrometry analysis. Identified reaction products were fluorenone, 2,2'-diformylbiphenyl, 1,4- and 9,10-anthraquinone, 9,10-phenanthrenequinone, 6H-dibenzo[b,d]pyran-6-one, three phenanthrol isomers, diphenic acid anhydride, 1-, 2-, 3-, 4- and 9-nitrophenanthrene, and 2- and 4-nitro-6H-dibenzo[b,d]pyran-6-one. Five other oxygenated products could only tentatively be characterized by their molecular formula. The identified compounds are compared with phenanthrene degradation products observed with other oxidants under simulated environmental conditions. The occurrence of identified compounds in ambient atmospheric samples is discussed.
