Sažetak
Rate constant for the oxidation of iron(II) and tert-butoxyl radical (t-BuO&middot ; )was measured using laser flash photolysis. t-BuO&middot ; radicals were generated by homolytic cleavage of di-tert-butyl peroxide in methanol at room temperature. Overall rate constant of the reactions competing with the reaction of interest was measured in a separate run using diphenylmethanol instead of iron(II). By using known rate constant of the reaction of diphenylmethanol with t-BuO&middot ; , the overall rate constant for the decay of t-BuO&middot ; radical in the system could be calculated. From the relative rate constant of oxidation of iron(II) with t-BuO&middot ; radical and t-BuO&middot ; radical decay rate constant, absolute rate constant was calculated, 3.4 ´ 108 M-1 s-1. The influence of the medium acidity on the rate constant was considered.
