Изучен радиолиз водных растворов трибутилфосфата, бутилацетата и изобутилацетата под действием γ-излучения в атмосфере аргона. Наблюдали гидролиз радикалов этих эфиров с образованием бутанола-1, бутанола-2, изобутанола и уксусной кислоты. Изучено влияние pH на выходы указанных продуктов радиолиза. Показано, что константы скорости гидролиза радикалов в ~108 раз превышают константы скорости гидролиза молекул сложных эфиров.

The radiolysis of aqueous solutions of tributylphosphate, butylacetate and isobutylacetate under the γ-radiation in an argon atmosphere has been studied. The hydrolysis of ester radicals with the formation of butanol-1, butanol-2, isobutanol and acetic acid has been observed. The effect of pH on the yields of these radiolysis products has been studied. It has been shown that the rate constants of hydrolysis of radicals are ~ 108 times higher than the rate constants of hydrolysis of ester molecules.
