The stable products of the low-pressure (4-8 torr (1 torr = 133.33 Pa)) gas-phase reactions of ozone with ethene, propene, 2-methylpropene, cis-2-butene, trans-2-butene, trans-2-pentene, 2,3-dimethyl-2-butene, and 2-ethyl- 1 -butene have been identified by using a photoionization mass spectrometer coupled to a stirred-flow reactor. The products observed are characteristic of (i) a primary Criegee split
臭氧与乙烯、丙烯、2-甲基丙烯、顺-2-丁烯、反-2-丁烯、反- 2-戊烯、2,3-二甲基-2-丁烯和2-乙基-1-丁烯已通过使用耦合到搅拌流反应器的光电离质谱仪进行鉴定。观察到的产物具有以下特征:(i)初级 Criegee 分裂成氧代烷烃(醛或酮)和 Criegee 中间体,(ii)反应
