Conclusions
-
1.
Di-tert-butyl peroxide, isobutylene, acetone, and methanol are formed in the SbCl5-catalyzed decomposition of tert-butyl hydroperoxide in acetonitrile solution.
-
2.
The decomposition takes place both heterolytically and homolytically. The contribution from homolysis is 1–5% of the total decomposition. The dependence of the rates of total decomposition and of homolysis on the concentrations of SbCl5 and tert-butyl hydroperoxide and the activation energies of these processes have been determined.
-
3.
The mechanism of the decomposition of tert-butyl peroxide in acetonitrile catalyzed by strong Lewis and Brönsted acids is discussed.
