The carbonyl products of the reactions of hydroxyl radicals with three vicinal diols (ethane-1,2-diol, propane-1,2-diol and butane-2,3-diol) have been identified and quantified. Hydroxyl radicals were produced by γ-radiolysis of N(2)O-saturated aqueous solutions. The reactions result in the formation of alkoxyl radicals (~15%) followed by β-fragmentation, and α-hydroxyl alkyl radicals that undergo H(2)O elimination. The latter process is part of a radical chain reaction at higher diol concentrations.
羟基自由基与三种邻二醇（乙烷-1,2-二醇、丙烷-1,2-二醇和丁烷-2,3-二醇）反应的羰基产物已被鉴定和定量。羟基自由基是通过 N(2)O 饱和水溶液的γ辐射分解产生的。反应生成烷氧基自由基（~15%），然后发生β断裂，生成α-羟基烷基自由基，后者通过 H(2)O 消除。后一过程是在较高二醇浓度下自由基链式反应的一部分。
