| 摘 要： | 二次有机气溶胶的形成是大气环境化学的研究热点。二羰基化合物对二次有机气溶胶形成具有重要的研究意义。由于二羰基化合物在液相中发生聚合反应,在液相中的分配大于Henry定律的预测值,影响二次有机气溶胶的形成。通过二羰基化合物乙二醛和甲基乙二醛在大气中光氧化和异相反应的研究,评述了二羰基化合物对二次有机气溶胶形成的研究发展。

| Abstract: | The formation of secondary organic aerosol （SOA） is the research focuses in atmospheric environmental chemistry. The dicarbonyl compounds have important research significance on the formation of secondary organic aerosol. Because dicarbonyl compounds polymerization in the liquid phase, the distribution of its value in the liquid phase is greater than the predicted value of Herry＇s law, affecting the formation of secondary organic aerosols. In the paper, by glyoxal and methylglyoxal atmospheric photo-oxidation and heterogeneous reaction, reviewed the dicarbonyl compounds on the formation of secondary organic aerosol research and development. |
