The mechanism of ozone-alkene reactions in the gas phase. A mass spectrometric study of the reactions of eight linear and branched-chain alkenes

摘要: The stable products of the low-pressure (4-8 torr (1 = 133.33 Pa)) gas-phase reactions 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 stirred-flow reactor. observed are characteristic (i) primary Criegee split an oxoalkane (aldehyde or ketone) intermediate, (ii)
