摘要

在水介质中，通过联苯与5,5-二甲基-1-吡啶- n -氧化物(DMPO)之间的竞争反应，估计了羟基自由基(oh)与脱氢二丁香酚、厚朴酚、厚朴酚、脱氢二氢丁香酚、脱氢二苯基醇和脱氢二酚等联苯化合物之间反应的近似速率常数。通过测量。oh自旋加合物的EPR信号高度的下降，得到了10(9)~ 10(10)M量级的速率常数。

Effective inhibition of hydroxyl radicals by hydroxylated biphenyl compounds.

In aqueous media, approximate rate constants for the reactions between hydroxyl radicals (.OH) and biphenyl compounds such as dehydrodieugenol, magnolol, honokiol, dehydrodidihydroeugenol, dehydrodivanillyl alcohol, and dehydrodicreosol were estimated by competition reactions for .OH between these biphenyls and 5,5-dimethyl-1-pyrroline-N-oxide (DMPO). By measuring the decrease in the height of the EPR signals of the .OH spin adduct, rate constants in the order of 10(9) to 10(10) M were measured.
