Burr, John G.

The deuterium content of the methane formed by radiolysis of deuterated acetic acids, and the tritium content of methane formed from tritiated acetic acids, both indicate that methane is forined from acetic acid almost cxclusively by a radical process in which the intermediate methyl radicals abstract hydrogen almost entirely from the methyl group of acetic acid. The isotope content of the hydrogen produced in these irradiations, together with the rates of hydrogen production (G(H₂)) values suggest, although less conclusively than for methane, a radical process as the origin for hydrogen. The origin of methane by a radical process in the irradiation of liquid acetic acid is compared with the evidence for a similar radical process in the fragmentation of CH₃COOH by electron impact in the highly dilute gas (mass spectrum).
