Oxidation Of Benzene

The oxidation of benzene to phenol in dilute aqueous solution by Co60 gamma rays and betatron X-rays (23 Mev. peak energy) is compared with the oxidationof Fe++ to Fe+++ under similar conditions. The ratio [Formula: see text]was the same for Co60 and betatron radiations. The yield for the Co60 radiations was about 10% greater than the apparent yield for the betatron radiations, the difference probably being attributable to dose determination at high energies (>1 Mev.). It is concluded that both reactions are independent of energy and dose rate over the ranges investigated.

Equilibria In Aqueous Solution

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.
