Temperature effect on zirconium benzoylacetonate extraction

Investigated is extraction of zirconium benzoylacetonate by the melt of eutectic naphthalene - diphenyl mixture depending on hydrogen ion concentration, masking reagents, temperature, ratio of phase volumes, metal ion concentration in aqueous phase. Found is temperature dependence of values of dissociation constants and benzoylacetone distribution in the water-melt system, as well as values of extraction, stability and distribution constants of the complex. In all the cases temperature dependence is of direct linear character
