Effect of Irradiation on the Lower Temperature Limit of Flame Propagation in the TODGA-Based Extraction Mixture

Resumo

The effect of accelerated electrons on the lower temperature limit of flame propagation in mixtures containing N, N, N′,N′-tetra-n-octyldiglycolamide and n-alcohol (n-decanol and n-nonanol) in various concentrations in Isopar-M was studied. In the extraction mixtures irradiated to a dose of 0.5 MGy, the lower temperature limit of the flame propagation (T_L) decreases insignificantly: by 2–3°C for the mixtures with 20% n-alcohol and by 6–11°C for those with 6% n-alcohol. The T_L values for the extraction mixtures, including irradiated mixtures, are no lower than 64°C.
