芳烃是城市地区环境空气中机动车尾气和非甲烷挥发性有机化合物的重要组成部分。最近提出脱烷基化是OH自由基引发的反应的重要途径，导致酚类化合物和/或氧杂环庚三烯的形成（Noda，J.，拉克萨默河莫利纳M.J.，2009.烷基苯的脱烷基化：甲苯、邻二甲苯、间二甲苯和对二甲苯+ OH反应中的重要途径。Journal of Physical Chemistry A 113，9658 -9666）。本文研究了OH自由基与间二甲苯和对伞花烃反应生成甲酚的情况，得到了生成甲酚的最高限
Aromatic hydrocarbons are important constituents of vehicle exhaust and of non-methane volatile organic compounds in ambient air in urban areas. It has recently been proposed that dealkylation is a significant pathway for the OH radical-initiated reactions, leading to the formation of phenolic compounds and/or oxepins (Noda, J., Volkamer, R.. Molina. M.J., 2009. Dealkylation of alkylbenzenes: a significant pathway in the toluene, o-, m-, and p-xylene + OH reaction. Journal of Physical Chemistry A 113,9658-9666.). We have investigated the formation of cresols from the reactions of OH radicals with m-xylene and p-cymene, and obtain upper limits of
