Radiolysis of sodium p-cumenesulfonate in aqueous solution

Abstract The reactions of hydrated electron e aq − , hydrogen atom (H) and CO 2 − (reducing species) as well as Cl 2 − , Br 2 − , N 3 − , OH, O − , SO 4 − radicals (oxidizing species) with sodium p -cumenesulfonate (SCS) in aqueous solution below minimum hydrotrope concentration have been studied by the method of steady-state and pulse radiolysis. The spectra of transient intermediates, leading to the final products, are presented. The rate constants for the reduction or oxidation reaction of the SCS are also given. The fate of the primary products of the SCS reaction produced during the pulse radiolysis under reductive or oxidative conditions is discussed.
