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.

The effect of bremsstrahlung gamma rays on the surface parameters of microporous amorphous zirconium silicate and on its ability for sorption is studied. The samples were irradiated using a betatron (electron accelerator) with the maximal energy of the g-quanta of 10 MeV and 24 MeV. The surface characteristics of the sorbents were studied by low-temperature adsorption/desorption of nitrogen. The experimental data were processed by BET, DR, and BJH methods. The results show that under exposure to Bremsstrahlung gamma rays the micropores of the sorbent under investigation are partly transformed in mesopores. The ability of zirconium silicate to absorb Sr2+ ions from an aqueous solution of strontium chloride is shown to increase noticeably after irradiation by 24-MeV bremsstrahlung gamma rays.

Kinetics Of

The kinetics of the reduction of copper(II) to copper(I) by carbon monoxide in aqueous solutions have been investigated at 120 °C and carbon monoxide pressures up to 1360 atm. The reaction is homogeneous and proceeds by two paths, one of which is virtually independent of carbon monoxide pressure due to the formation of a stable cuprous carbonyl complex Cu(CO)+. The second reaction path contains both a pH-dependent and pH-independent component. The rate-determining step in both paths appears to be the decomposition of a carbon monoxide insertion complex by a cupric ion. Complexing ligands such as acetate were observed to have a minor inhibiting effect on the overall reaction.
