| 中文摘要 |
| 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。 |
| 英文摘要 |
| The reaction of isoprene-O3 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 O3 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 CO2,etc.The reaction mechanism for the ozone oxidation of isoprene is briefly discussed. |
