Etude de la radiolyse du pentane normal a 77 K par capture des radicaux apres l'irradiation

Abstract

n-Pentane was irradiated in the solid phase at 77 K. Post-irradiation scavenging of radicals by dissolving at 110 K the irradiated pentane in a propane-oxygen mixture lowers the decanes and pentenes G-values to an extent of 40–60%. The principal experimental results are: (1) a radical G-value of 2·76; (2) a radicalar distribution of 30% in primary radicals and 70% in secondary radicals; (3) a rough dismutation-combination ratio of 2·1 at 120 K.
