Abstract
Oxygenated 1 M aqueous solutions of 2-methyltetrahydrofuran (MTHF) or D-glucose were .gamma.-irradiated, and G(total peroxide) was determined as a function of dose rate and temperature. Whereas MTHF was oxidized by a chain process, D-glucose was not. The peroxyl radicals derived from D-glucose rapidly eliminate HO2.cntdot.. At natural pH HO2.cntdot. (pK = 4.75) is largely deprotonated. O2.cntdot.- does not propagate a chain.
