GC和GC／MS法研究SO_2和正己烷的气相光化学反应──大气光化学反应模拟研究（Ⅴ）

AN INVESTIGATION ON THE PHOTOCHEMICAL REACTIONS OF SULFUR DLOXIDE AND HEXANE

报道对大气中ＳＯ２与气相有机污染物的光化学反应模拟研究的另一新结果，利用ＧＣ和ＧＣ／ＭＳ法确定了反应的主要产物、探讨了几种影响因素，并依自由基反应机理阐明了几种主要产物的形成过程。

The photochemical reactions of sulfur dioxide and hexane in the pre-sence or absence of oxygen systems were studied. A series of products such as al-cohols,ketones, esters, hydrocarbons and organic sulfur compounds were identified by GC/MS.According to the characters of such compeunds and the free radical theory,the mechanism of these photochemical reactions were suggested. These re-sultsare very important to the studies of chemistry of air pollution and acid rain.
