Abstract
It has been shown that a
salicylatoberyllium complex can be extracted from aqueous solutions by
aliphatic alcohols. The distribution ratio is a symmetrical function of the
logarithm of the free ligand concentration and passes through a maximum value ;
the stability constants of the mono- and bis(salicylato)beryllium complexes
have been determined from the data for points of equal extraction. The values
obtained in this way are β1 = 4.1 x 1012 and β2
= 4.3 x 1022, in an ionic strength of 0.15. They agree fairly well
with those obtained by pH-titration procedures, which are β1 = 6.1 x 1012
and β2 =7 x 1022.
