Resumo

This study is devoted to the effect of complete deuteration of the ethylene glycol carbon skeleton on the formation of its radiation-induced free-radical transformations products in deaerated aqueous solutions at pH 7.00 ± 0.10 and a dose rate of 0.064 ± 0.002 Gy/s. It has been established that the chain process of fragmentation of carbon-centered ethylene glycol radicals (∙CH(OH)CH2OH) plays an important role in the formation of acetaldehyde. The replacement of protium atoms located at carbon atoms by deuterium decreased the radiation-chemical yield of acetaldehyde in aqueous 1 M solutions of diols by a factor of 8. The results of this study indicate that the use of deuterium exchange at the carbon skeleton of organic molecules is a promising way for increasing their resistance to radiation-induced free radical fragmentation processes.
