摘　　要：用双通道Ｈ２Ｏ２分析系统研究了室温条件下异戊二烯与Ｏ３气相暗反应体系中有机氢过氧化物和Ｈ２Ｏ２的产率．３次实验测得有机氢过氧化物的产率分别为３．８％、４．３％和３．９％，平均为４．０％；Ｈ２Ｏ２的产率分别为２．２％、１．６％和１．８％，平均为１．９％．探讨了异戊二稀与Ｏ３反应体系中有机氢过氧化物和Ｈ２Ｏ２的生成机理．he atmospheric reaction of isporene with O 3 was simulated under the dark and room temperature in the 28 5L quartz reactor coupled with a Long Path Fourier Transform Infrared Spectrometer,while the Dual Channel H 2O 2 Analytical System was used to determine the production of organic hydroperoxides and H 2O 2.Yields measured respectively in the three repeated experiments are 3 8%,4 3% and 3 9% for organic hydroperoxides with the average of 4 0%,and 2 2%,1 6% and 1 8% for H 2O 2 with the average of 1 9%.The formation mechanisms of organic hydroperoxides and H 2O 2 were briefly discussed.
