摘要：

Metal nitrates solvated by octyl(phenyl)-N, N-diisobutylcarbamoylphosphine oxides exhibit a limited solubility in many alkane diluents even in the presence of a modifier such as tributyl phosphate. The solubility is a nonmonotonous function of the aqueous nitric acid concentration. The solubility of Nd(III) nitrate strongly increases with temperature, branching of the diluent molecule, and the concentration and the molecular weight of a trialkyl phosphate modifier. Empirical equations were derived which describe the solubility of Nd(III) nitrate, the distribution ratio of Nd(III), and the distribution ratio of nitric acid as functions of the nitric acid and Nd(III) concentrations in the equilibrium aqueous phase.
