BS>It was found that a salicylatoberyllrum complex can be extracted from aqueous solutions by aliphatrc 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 were determined from the data for points of equal extraction. The values obtained in this way are beta /sub 1/=4.1 x 10/sup 12/ and beta /sub 2/ = 4.3 x 10/sup 22/, in an ionic strength of 0.15. They agree fairly well with those obtained by pH-titration procedures, which are beta /sub 1/ = 6.1 x 10/sup 12/ and beta /sub 2/ =7 x 10/sup 22/. (auth)
