Primary yields in the γ-radiolysis of gaseous aliphatic amines

Abstract

Yields of H₂ and CH₄ from methyl-, trimethyl- and ethyl-amine vapours γ-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_H2, G_eG_H and relative rate constants for some reactions of H atoms have been calculated. Except for methylamine the values of G_e 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.
