Abstract

The reaction of O(³P) with alkenes plays an important role in combustion. CH₃ and C₂H₅ were monitored as the direct products of the reactions of O(³P) with isomeric three butenes (1-,trans-2-, and iso-butenes) by using photoionization MS. ) The signal intensity of CH₃(m/z = 15) increased linearly with the increase of initial concentration of O atoms for all the three butanes. The branching ratios of the CH₃ product channel were determined as 0,05, 0.52, and 0.24 for the reactions of O atoms with 1-butene, trans-2-butene, and isobutene, respectively. The yields were determined as 0.63 for both 1-butene and trans-2-butene. The results were consistent with the prediction regarding the site-selectivity for the addition of O atom to the double bond of the substituted alkenes. Original is an abstract.
