Radiolysis of methanol adsorbed on synthesized zeolite was investigated by means of product analysis. Molecular hydrogen, formaldehyde, and ethylene glycol are produced as major products. The <I>G</I>-value for the formation of H<SUB>2</SUB> increases with increasing amount of methanol adsorbed on zeolite and approaches ca. 2.1 at about 10<SUP>−2</SUP> mol of methanol per g of zeolite, where the coverage of methanol is approximately unity and <I>G</I>-values of ca. 1.0 are observed for formaldehyde and ethylene glycol. Addition of an electron scavenger causes decrease in <I>G</I>(H<SUB>2</SUB>). However, the hydrogen formation is not completely suppressed by N<SUB>2</SUB>O, SF<SUB>6</SUB>, or CCl<SUB>4</SUB>. Kinetics in solution is useful for the interpretation of results and allows the estimation of the <I>G</I>-value for the generation of electron in zeolite and of its relative reactivity toward methanol and some electron scavengers.
