Abstract
The effect of radiolysis and postradiation acid hydrolysis on the composition of the degradation products of tributyl phosphate (TBP, 30 wt %) in acidified Izopar-M has been studied. It has been found that the simultaneous presence of nitric acid and isoparaffins in the irradiated solution has a protective effect on TBP. The main radiolytic products are due to the nitration, nitroxylation, and alkylation of TBP. Upon the postradiation thermolysis, nitro derivatives and nitrates decomposed with partial regeneration of TBP. Heating above 110°C also provoked the dealkylation of radiolytic products with the formation of volatile compounds, which increased the fire and explosion hazard of using irradiated extraction mixtures.
