The Liquid-phase γ-Radiolysis of Benzene-Nitrous Oxide Mixtures

Abstract The γ-radiolysis of the benzene-nitrous oxide liquid mixtures has been studied at room temperature and at 0°C, the mixing ratios covering almost all the range from pure benzene to pure nitrous oxide. Phenol was found to be one of the main products; its G-value is about a half of that of nitrogen at the lower concentration of nitrous oxide. Kinetic analysis shows that the G-values of electrons from benzene are 3.2±0.2. An empirical equation for expressing the G-value of nitrogen from the benzene solution of nitrous oxide proposed by Hentz and Sherman (J. Phys. Chem., 73, 2676 (1969).) was examined. The agreement was very poor at higher concentrations of nitrous oxide. Possible reasons were discussed.
