| Abstract: | The features of cumene oxidation, α-phenylisopropyl hydroperoxide (ROOH) decomposition, and free radical formation in the
presence of cetyltrimethylammonium bromide (CTAB) were studied by the kinetic methods and TLC product analysis. It was found
that CTAB catalyzes ROOH decomposition to free radicals. The efficiency of an initiating system CTAB—ROOH is by a factor of
2.5 higher than that of a combination CTAB with α-phenylethyl hydroperoxide. In addition, CTAB catalyzes the reactions of
ROOH with α-tocopherol and 2,2′-bis2-(p-dimethylaminophenyl)indane-1,3-dione]. The kinetic characteristics of these reactions were determined.
