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 to account for the observed products: CH/sub 3/CHO, H/sub 2/CO, CO/sub 2/, CH/sub 4/, CH/sub 3/C(O)C(H)(OH)CH/sub 3/, H/sub 2/C/double bond/C/double bond/O, H/sub 2/O, 2-butanone, 2,3-epoxybutane, CH/sub 3/C(O)C(O)CH/sub 3/, and HC(O)C(O)H. This work again indicates that the simple hot ester hypothesis needs to be critically reconsidered for gas-phase ozonolysis.
