Abstract
The radiolysis of 1-propanol without heating and in a boiling state under the action of accelerated (8-MeV electrons) was investigated. At room temperature, aldehydes dominated among molecular products. Unlike γ-radiolysis, monohydric alcohols were the second most important fraction. The yields of formation of aldehydes, monohydric alcohols, and diols in boiling 1-propanol were approximately equal. Boiling increased the weight fraction of products heavier than 1-propanol to 74%, whereas this fraction was 57% at room temperature. As follows from the analysis of products, boiling accelerated the dissociation of radicals and radical cations and facilitated radical exchange and combinations processes. The yields of 1-propanol degradation were 10.1 ± 0.9 and 13.3 ± 0.9 molecule/100 eV at room temperature and in a boiling state, respectively.
