polycyclic aromatic hydrocarbons expected to be in the gas phase in ambient atmospheres and are subject to nighttime degradation by gas-phase reactions with the nitrate (NO3) radical. Using a relative rate method, rate constants for the gas-phase reactions of NO3 radicals with a series of alkylnaphthalenes have been measured at 298 +/- 2 K and atmospheric pressure of air. The compounds studied were 1- and
萘及其甲基,乙基和二甲基衍生物是半挥发性的多环芳族烃,预计会在环境大气中处于气相状态,并且会通过与硝酸根(NO3)的气相反应在夜间降解。使用相对速率法,已在298 +/- 2 K和大气压力下测量了NO3自由基与一系列烷基萘的气相反应速率常数。研究的化合物为1-和2-甲基萘(1-和2-MN),1-和2-乙基萘(1-和2-EN)以及10种二甲基萘异构体(1,2-,1,3-, 1,4-,1,5-,1,6-,1,7-,1,8-,2,3-,2,6-和2,7-DMN)。在加利福尼亚州里弗赛德市的采样显示,这些烷基萘在环境空气中很容易检测到,但1,8-DMN除外。
