Conclusions
-
1.
On the basis of the kinetic relationships for the decomposition ofα-phenylethyl hydroperoxide in the presence of catalytic amounts of complexes of Cu(II) with o-phenanthroline (o-P) it was concluded that an intermediate complex is formed between the catalyst and the hydroperoxide.
-
2.
The rates of oxidation of etbylbenzene and decomposition ofα-phenylethyl hydroperoxide vary differently with variation in the composition of the catalytic mixture. It is supposed that the CuSt2· (o-P) complex takes part not only in the radical formation stage but also in other stages of the process and, in particular, in the chain propagation stage.
