Abstract

The distribution ratio D of HgCl₂, HgBr₂ and HgI₂ between a polyphenyl phase (37 mole % biphenyl, 48% o‐terphenyl and 15% m‐terphenyl) and a mixture of molten LiNO₃ and KNO₃ was determined radiometrically. Log D was found to increase linearly with 1/T in the range 150–200° and values of ΔH° in this range were derived. Variation of the mole ratio K/Li in the melt between 1.00 and 1.86 (eutectic ratio = 1.33) was shown to cause considerable variations in D. The decrease of D on addition of potassium halide to the melt was found consistent with the formation of inextractable anionic complexes (HgX₃⁻ and HgX₄^) formation constants for these complexes are given.
