Abstract

Low-temperature chlorination of uranium metal in the TBP-TCE-Cl2 systems was studied. Dissolution of uranium in the dipolar aprotic solvent proceeds with formation of U(IV) compounds. The activation energy of this process is 31.24 kJ mol−1, and relative reaction order with respect to Cl2 is 2. The effect of TBP concentration on chlorination was examined. The chlorination rate sharply increases at a water content in the TBP-TCE system of 0.2–0.6 vol %.
