Abstract

The effect of polyphenol sulfides (PPS) and dithiolthione, the sulfur-containing derivative of acetone anil, on the decomposition of cumyl andn-decyl hydroperoxides (DHP) studied. The decomposition of cumyl hydroperoxide (CHP) in the presence of PPS is a complex multistep autocatalytic process during which an efficient catalyst for CHP decomposition is formed from the initial PPS. The PPS catalyst for CHP decomposition is deactivated in the reaction with peroxy radicals. Kinetic characteristics of the reaction between polyphenol sulfides and CHP are determined. Dithiolthione catalytically decomposes CHP and reacts with n-decyl hydroperoxide DHP in the stoichiometric ratio
