Radiolysis of gaseous isobutene by 60Co γ-rays. III. Low boiling point condensation products

Abstract

During the γ-rays irradiation of gaseous isobutene the following low boiling point condensation products are formed: 2-methyl-1-butene, 2-methyl-2-butene, 1,1-dimethyl-cyclopropane, 3-methyl-1-butene, neopentane, isopentane, and n-pentane. All these products are formed in radical processes, as shown by the scavenging action of nitric oxide. The formation of the pentenes results from the reaction of the methylene radical with isobutene, whereas the reaction of the methyl radical with the monomer accounts for the production of pentanes.
