| 摘 要： | 研究室温下石英玻璃反应器中异戊二烯与Ｏ３的暗反应，长光路ＦＴＩＲ法得到的实验结果表明，在本模拟反应条件下异戊二烯－Ｏ３反应体系中，主要产物甲基丙烯醛、甲基乙烯基酮和ＨＣＨＯ的产率分别为３７．４％、２０．２％和５５．１％，通过红外谱图的分析可确定反应中的其它产物为ＨＣＯＯＨ、ＣＯ和ＣＯ２等，对异戊二烯与Ｏ３的反应机理进行了探讨。

| Abstract: | The reaction of isoprene O 3 in the dark was studied by means of the Long Path Fourier Transform Infrared (LP FTIR) method.Experiments were carried out in the evacuable quartz reactor with the volume of 28 5L under the room temperature.The experiment results indicated that the major products in the isoprene O 3 reaction systme are methacrolein,methyl vinyl ketone and HCHO,with a yield of 37 4%,20.2% and 55 1%,respectively.Other products identified in the FTIR spectrum are HCOOH,CO and CO 2,etc.The reaction mechanism for the ozone oxidation of isoprene is briefly discussed. |
