✦ Synopsis

Rate constants have been determined for the reactions of SO4with a series of alkanes and ethers. The SO, radical was produced by the laser-flash photolysis of persulfate, SZO: -.

For methane, only an upper limit of 1 x lo6 M-' s-* could be determined. For ethane, propane, and 2-methylpropane, rate constants of 0.44, 4.0, and 10.5 x lo7 M-' s-l were found. For ethyl and n-propyl ether, rate constants of 1.3 x 10' and 2.2 x 10' M-' s-' were found and for 1,4-dioxane and tetrahydrofuran, rate constants of 7.2 x lo7 and 2.8 x 1 0 ' were obtained. The reaction of SO,with ally1 alcohol was also studied and found to have a rate constant of 1.4 x lo9 M-' s-'.

An important step in the initial oxidation of hydrocarbons at low to intermediate temperatures is the abstraction of H by hydroperoxyl radical (HO(2)). In this study, we calculate energy profiles for the sequence: reactant + HO(2) → [complex of reactants] → transition state → [complex of products] →
