Abstract

The rate constant ratio k4/k5 of the reactions of α-phenylethyl radicals (.RH) with DPPH (k4) and with 9,10-anthraquinone (k5) was calculated by measuring the quantum yields of the trapping of RH by DPPH: k4/k5=44±16 (at 25°C).

Abstract

Был измерен квантовый выход реакции α-фенил-этильных радикалов (.RH) с ДФПГ в присутствии второй радикальной ровушки 9,10-антракинона (Q). На основании измерений было рассчитано отношение констант скоростей реакций .RH с ДФПГ (k4) и с Q (k5): k4/k5=44±16 (при 25°C).
