Analysis of radiolysis products of aqueous uracil + N2O solutions
Abstract
Various products from the irradiation of solutions of uracil + N2O with 60Co gamma rays were separated by paper chromatographic technique using 14C labelled materials. Identity of the isolated products was investigated by spectrophotometric and kinetic decomposition studies. Thus at least eight radiolytic products of uracil such as cis- and trans-uracil glycols, 5-hydroxy-6-hydro and 6-hydroxy-5-hydro compounds, isobarbituric acid and three dimeric products were identified. Yields of these products were determined at different pH values; a good material mass balance was achieved; the mechanism involved is discussed.
