Die Oxydation von Benzo(a)Pyren-Chinonen

Abstract

The autoxidation and oxidation with hydrogen peroxide (I) of intermediate products of BP oxidation - 6-hydroxy-BP and three BP quinones have been studied in aqueous solution. The reaction of autoxidation of BP derivates is of first order which rate does not depend on the structure of quinone. The oxidation with I is the reaction of mixed first-second order. The estimation of concentration effect of I on the oxidation of three BP quinones indicates that reaction rate depends on the initial concentration of oxidant and on the structure of BP quinones. The rate as well as autoxidation and oxidation wth I decrease during further oxidation of BP and BP derivates because of the inhibitory effect of some reaction products such as BP quinones.
