摘要
用紫外线、臭氧降解气相中二甲苯(邻、间、对二甲苯),分别考察了在不同的反应条件下二甲苯的降解情况。比较了在空气或氮气的不同反应系统中二甲苯的降解情况,并对二甲苯在空气中的光降解产物及其反应历程进行了探讨;实验结果表明,在相同条件下邻二甲苯的光降解速率最大,二甲苯的光降解过程中都有中间产物生成。
The degradation of xylene (p-,m-,o-xylene) by ultraviolet light and ozone was investigated in different conditions. The degradation reactions of xylene in air and nitrogen were compared. The intermediate products of xylene in the photo-degradation reaction in air and the mechanism were discussed. The experiment resuits indicated that the photo-degradation rate of p-xylene was more than the others, and the intermediate products were detected by direct GC/FID analysis under the same conditions.
