Abstract—

The effect of the boiling state on the reaction mechanism of 11 free radicals formed upon irradiation of 1-propanol with 8 MeV accelerated electrons is considered. Compared to radiolysis at room temperature, radiolysis at boiling results in an increase in 1-propanol degradation yield from (10.1 ± 0.9) to (13.3 ± 0.9) molecule/100 eV. Boiling shows the largest effect on the radilytic cleavage of the C(1)–H and C(2)–H bonds and almost doubles the yield of hydroxyalkyl radicals. In particular, the boiling effect is due to the suppression of the cage effect, a decrease in the relative role of intermolecular relaxation, and an increase in the processes of radicals exchange and combination.

沸腾对羟烷基自由基形成与衰变机理的影响

摘要—

考虑了沸腾状态对1-丙醇经8 MeV加速电子辐照形成的11个自由基的反应机理的影响。与室温下的辐射分解相比，沸腾下的辐射分解导致1-丙醇降解产率从（10.1±0.9）分子增加到（13.3±0.9）分子/ 100 eV。沸腾显示出对C（1）–H和C（2）–H键的辐射裂解最大的影响，并且羟烷基自由基的产率几乎翻倍。尤其是，沸腾作用是由于笼罩作用的抑制，分子间弛豫的相对作用的降低以及自由基交换和结合过程的增加而引起的。
