Abstract
The effect exerted by irradiation with accelerated electrons on the thermolysis kinetics in two-phase systems consisting of 14 M aqueous HNO3 and FS-13 diluent or 0.1 M solution of 2,2′-bipyridine-6,6′-dicarboxylic acid bis(N-ethyl-4-hexylanilide) in FS-13 was determined. Samples were irradiated at an electron accelerator at a dose rate of 10 kGy h–1 to integral doses of 0.1, 0.5, and 1 MGy. The mixtures were heated in an autoclave at 170 and 200°С. A study of the heat and gas evolution processes occurring in the course of thermolysis of extraction mixtures irradiated to doses of 1 MGy showed that conditions for the development of autocatalytic oxidation are not created even in the systems kept for 2 weeks in contact with 14 M HNO3.
