Abstract

The kinetics of ethylbenzene oxidation in the presence of acetic anhydride, the kinetics of acetic anhydride reaction with cyclohexyl hydroperoxide, and the composition of the products of the above reactions were studied in order to evaluate the initiating abilities of 1-phenylethyl and cyclohexyl peroxyacetates generated in situ and to determine the directions of reactions. Anhydride additives significantly accelerated the oxidation of ethylbenzene and the degradation of cyclohexyl hydroperoxide with the predominant formation of corresponding ketones. It was found that the acceleration of ethylbenzene oxidation was due to the homolytic degradation of a peroxy ester, which results in the formation of methyl phenyl carbinol and benzaldehyde (ethylbenzene) or cyclohexanol (cyclohexyl hydroperoxide). The importance of the homolytic degradation of peroxy esters was evaluated using a mixed-initiation method (ethylbenzene) or by measuring the consumption of an inhibitor (cyclohexyl hydroperoxide).
