Abstract

Molecular weights of uranyl nitrate and thorium nitrate solutions in TBP were determined using vapor pressure osmometry. The results seem to show that in carbon tetrachloride uranyl nitrate forms a di‐solvate only, whereas in acetone solution this complex is partly dissociated. Thorium nitrate results have been explained assuming a mixture of two complexes with TBP‐a di‐solvate and a tri‐solvate. The equilibrium constant for the reaction Th(NO₃)₄ · 2TBP + TBP ⇄ Th(NO₃)₄ · 3TBP was found to be K_x = 30 at 25°C.
