Abstract

Termination rate constants of peroxy radicals of seven polyatomic esters in benzene and perflouorooctane media have been measured by pulse photolysis. Recombination of peroxy radicals for all esters examined proves to be diffusion controlled. Reactivity of peroxy radicals in the termination reaction grows with increasing number of ester groups.

Abstract

Методом импульсного фотолиза измерены константы скорости реакции гибели пероксильных радикалов семи многоатомных сложных эфиров в среде бензола и перфтороктана. Режим реакции рекомбинации пероксильных радикалов всех сложных эфиров определен как диффузионный. Сделан вывод о возрастании реакционной способности пероксирадикалов в акте рекомбинации с ростом числа сложноэфирных группировок в молекуле.
