在294 K和530 Pa（4 Torr）下，用停流反应器和光电离质谱仪研究了臭氧与反式-2-丁烯的气相反应。反应物和产物的浓度被确定为反应时间的函数。提出了一种机理来解释所观察到的产物：CH_3CHO，H_2CO，CO_2，CH_4，CH_3C（O）C（H）（OH）CH_3，H_2C = C= O，H_2 O，2-丁酮，2，3-环氧丁烷，CH_3C（O）C（O）CH_3和HC（O）C（O）H。这项工作再次表明，简单的“热”酯假设需要严格重新考虑气相臭氧分解。
The reaction of ozone with trans-2-butene has been studied in the gas phase at 294 K and 530 Pa (4 Torr) by using a stopped-flow reactor coupled to a photoionization mass spectrometer. The concentrations of reactants and products were determined as a function of reaction time. A mechanism is proposed toaccount for the observed products: CH3CHO, H2CO, C02, CH4, CH3C (0) C (H)(0H) CH3, H2C= C= 0, H20, 2-butanone, 2, 3-epoxybutane, CH3C (0) C (0) CH3, and HC (0) C (0) H. This work again indicates that the simple “hot” ester hypothesis needs to be critically reconsidered for gas-phase ozonolysis.
