Resumo
The thermal stability of mixtures of TBP and its solutions in diluents with uranyl nitrate (UN) at 150–200°C was evaluated. Exothermic self-accelerating oxidation processes (thermal explosions) arise in mixtures with TBP at 160–170°C. In mixtures of UN with solutions of TBP in diluents, the intensity of the exothermic processes is appreciably lower. The presence of the extractant in UN solutions fed to high-temperature operations gives rise to the hazard of the initiation of intense exothermic processes.
