OH与1-和2-甲基萘、1，3-和2，3-二甲基萘的气相反应。在模拟大气条件下，在10 m3的烟雾室中对苊和苊进行了研究。反应速率，相对于萘= 1.0，1 -甲基萘，1.5，2-甲基萘，2。1; 1，3-二甲基萘，0.9; 2，3-二甲基萘，0.9;苊，2.9;和苊烯，5.8。固相微萃取（SPME）与气相色谱/质谱（GC/MS）相结合，用于分析有机反应产物，从而避免了在以前使用的冷指捕集程序中观察到的文物的生产。反应产物主要是萘与OH自由基反应生成的同系物。
The gas-phase reactions of OH with 1- and 2-methylnaphthalene, 1,3- and 2,3-dimethylnaphthalene. acenaphthylene and acenaphthene were investigated under simulated atmospheric conditions in a 10m(3) smog chamber. The rates of reaction, relative to naphthalene = 1.0, were 1 -methylnaphthalene, 1.5; 2-methylnaphthalene, 2. 1; 1,3-dimethyinaphthalene, 0.9; 2,3-dimethyinaphthalene, 0.9; acenaphthene, 2.9; and acenaphthylene, 5.8. Solid phase microextraction (SPME) in combination with gas chromatography/mass spectrometry (GC/MS) was used to analyze the organic reaction products, thus avoiding the production of artifacts observed in the previously used cold finger trapping procedure. Reaction products were mainly homologs of those formed in the reaction of naphthalene with OH radicals.
