Studies on the Interaction of Anthraquinone Triplet and α‐Phenylethyl Hydroperoxide in Benzene and Chlorobenzene

Abstract

AbstractThe quantum yields of the formation of products as well as their temperature dependence during the photochemical decomposition of α‐phenylethyl hydroperoxide (HROOH) have been measured in the presence of triplet anthraquinone (TQ) in air‐saturated benzene and chlorobenzene at 301–373 K. The photochemical and thermal decomposition of HROOH have been compared. Experimental results and their mathematical simulation indicate that in the reaction of TQ with HROOH peroxy radicals, HRO2, are generated. According to the measurements magnified image at T = 30 K, and the energy of activation of the reaction magnified image is about 5.9 kJ mol−1.
