The Radiolysis of Acetic Acid in Aqueous Solutions and Acetic Acid-Water Mixtures

Authors: Lj. Josimović , I. Draganić

The radiation chemical yields of stable products were measured in deaerated and oxygenated solutions at low absorbed doses(~<10 krad), different pH values(1-3 and 7.8) and various acetic acid concentrations(0’1-17mol dm-a). For a dilute solution(0″1mol dm-a) the results obtained support a simple reactions cheme.At larger acetic acid concentrations yields of stable products change proportionally to the electron fraction of acetic acid in irradiated mixture. Determinations of molecular hydrogen in deaerated solutions and some measurements of nitrite ion yield in the presence of nitrate point to the reaction of acetic acid with the precursor of the hydrated electron. Optical absorption spectra of intermediates in deaerated acetic acid-water mixtures were obtained by pulse radiolysis.
