Аннотация:When a circulating extraction mixture of 30% TBP in Isopar-M, saturated with 3.4 mol L−1 nitric acid, is irradiated with a dose of up to 2000 kGy, products are formed that reduce the value of the lower temperature limit of flame propagation (Tl) from 74 to 52 ℃ and worsen the hydrodynamic properties. A comparison of regeneration methods of an irradiated extraction mixture showed that the method of fractional vacuum distillation is the most effective for increasing the Tl value. Regeneration with carbonate solutions increases Tl, removes non-volatile radiolysis products, and moreover is the simplest and most economical regeneration method.
