The Schiff base, N-n-butylsalicylideneimine, extracts more than 99.8% beryllium into toluene from dilute aqueous solution. The distribution of beryllium has been studied in the pH range 5-13 and is discussed in terms of the several complex equilibria in aqueous solution. The stability constants of the complexes formed between beryllium and the Schiff base are log β1 11.1 and log β2 20.4, and the distribution coefficient of the bis complex is 550. Over most of the pH range, hydrolysis of the Be2+ ion competes with complex formation and provides a means of measuring the hydrolysis constants. They are for the reactions: Be(H2O)42+ ↔ 2H+ + Be(H2O)2(OH)2, log*β2 - 13.65; Be(H2O)42+ ↔ 3H+ + Be(H2O)(OH)3-, log*β3 -24.11.

The complexation of beryllium (II) with 3,5-dinitrosalicylic acid in aqueous 0.1 ᴍ KNO3 medium has been investigated potentiometrically, which evince the formation of 1 : 1 and 1 : 2 complexes, predominating in the pH ranges 2.7 —4 and 4—9, respectively. The values of log K1 and log K2, determined by alternative methods, have been found to be 7.13 and 5.29 respectively. The value of overall change in free energy (ΔF) accompanying the reaction has been found to be —17.34 Kcal/mole at 35°C.
