Primary Yields in the y-Radiolysis of Gaseous Aliphatic Amines

Abstract

Yields of H2 and CH4 from methyl-, dimethyl-, trimethyl- and ethyl-amine vapours y-irradiated at room temperature have been measured. The effects of dose, pressure, electron and free radical scavengers on these yields have been studied. From the decreases in G(H2) in the presence of scavengers values for G^,, Gc, Gh and relative rate constants for some reactions of H atoms have been calculated. Except for methylamine the values of Ga obtained in this way are lower than those obtained from measurements of the energy of ion pair formation, W. Ethylenediamine is a product from radiolysis of methylamine but dimethylhydrazine is not.
