摘要
本文研究了二硝基芘异构体在模拟大气条件下的光化学反应，结果表明反应速率呈二级动力学关系。除光源变化的影响外，二硝基芘异构体在不同气氛中，反应速率不同，存在着氧的猝灭和氧化作用。而不同的异构体之间，相应的反应速度也不同。光解产物中存在硝基羟基类化合物、醌类和二聚体。毒理实验表明，光解产物致突变性下降。
Photo reaction of dinitropyrenes in simulated atmospheric conditions was studied.The photochemical reaction rate was found to be of the second order.Different reactionrates correspond to different dinitropyrene isomers and to different carrier gases with possibly the competition of the quenching and oxidation by oxygen.The photoreaction productswere identified as pyrenequinone,multi-,and mono-nitrohydroxypyrenes,dipyrenone etc.The mutagenicity of photochemical reaction products is lower than that of the original dini-tropyrenes.
