Abstract

The kinetics of positive ion and electron scavengin gin certain n-alkanes, cycloalkanes, branched alkanes, aromatic hydrocarbons and in some polar compounds (ethers, dimethyl-formamide) have been investigated.

The non-homogeneous kinetic approach gives satisfactory agreement with experimental Results for n-hexane, cyclohexane, iso-octane and 2,3-dimethylbutane. Differences between positive ion and electron scavenging for ethers have been observed and ascribed to the complex structure of the corresponding positive ions. For benzene and dimethylformamide the homogeneous kinetic equation gives the best agreement with experimental results.

Characteristic parameters such as G_fi, G_gi, reactivity coefficients α, rate constant of ion scavenging k_s, geminate recombination parameters for several solvents λ, and the most probable distances of electron thermalization have been determined or calculated.

The effect of molecular structure on the ionic reactions has been discussed.

辐照有机液体中离子的清除

研究了某些正构烷烃、环构烷烃、支链烷烃、芳烃和某些极性化合物(醚、二甲基甲酰胺)的正离子和电子清除动力学。正己烷、环己烷、异辛烷和2,3-二甲基丁烷的非均相动力学方法与实验结果吻合较好。对醚的正离子和电子清除能力之间的差异已被观察到，并归因于相应正离子的复杂结构。对于苯和二甲基甲酰胺，均相动力学方程与实验结果吻合最好。表征参数如Gfi、Ggi、反应性系数α、离子清除速率常数ks、几种溶剂的双相复合参数λ和最可能的电子热化距离已被确定或计算。讨论了分子结构对离子反应的影响。
