ClONO{sub 2}与HCl在硝酸三水合物（NAT）和二水合物（NAD）和冷冻硫酸溶液上的反应作为反应物浓度和平流层温度代表的函数进行了研究。使用配备有化学电离质谱仪检测器的流管反应器。测得的反应吸收系数显示出强烈的依赖于温度在恒定的H{sub 2}O分压。NAT的这些结果在定性上与Abbatt和Molina的结果相似，但在定量上与Abbatt和Molina的结果不同。N{sub 2}O{sub 5}和ClONO{sub 2}在冷冻硫酸上的水解效率远低于在液体溶液中的水解效率。这些结果的平流层的非均质化学的影响进行了讨论。参考文献19篇，图5，2个标签。
The reaction of ClONO{sub 2} with HCl on the nitric acid trihydrate (NAT) and dihydrate (NAD) and on frozen sulfuric acid solutions was studied as functions of reactant concentration and temperature representative of the stratosphere. A flow tube reactor equipped with a chemical ionization mass spectrometer detector was used. The measured reactive uptake coefficient shows a strong dependence on temperature at constant H{sub 2}O partial pressure. These results for NAT are qualitatively similar to but quantitatively different from those of Abbatt and Molina. The hydrolysis of N{sub 2}O{sub 5} and ClONO{sub 2} on frozen sulfuric acid were measured to be far less efficient than that in liquid solutions. The implications of these results to the heterogeneous chemistry of the stratosphere are discussed. 19 refs., 5 figs., 2 tabs.
