Abstract:
Product yields in the reaction of e~, -H, -OH and Cl/ with uracil and uracil- have been determined
quantitatively in 60Co y-irradiated aqueous uracil solutions in the presence of suitable scavengers.
Good material balances between G(—uracil) and G(total products) have been obtained in all cases.
The products determined were: uracil dimer, alloxan, alloxantin, uracil czj-glycol, uracil /ra/u-glycol,
dialuric acid, isobarbituric acid, 5-hydroxydihydrouraciI, 6-hydroxydihydrouraciI, dihydrouracil,
formylurea, 5-hydroxyhydantoin, parabanic acid, urea and alcohol adducts. Based on the yields
of these products and the available literature, mechanisms are proposed and discussed.
