Effect of sulfur-containing phenols and amines on the decomposition of hydroperoxides

The effect of polyphenol sulfides (PPS) and dithiolthione, the sulfur-conta ining derivative of acetone anil, an the decomposition of cumyl and n-decyl hydroperoxides (DHP) studied. The decomposition of cumyl hydroperoxide (CH P) in the presence of PPS is a complex multistep autocatalytic process duri ng which an efficient catalyst for CHP decomposition is formed from the ini tial PPS. The PPS catalyst for CHP decomposition is deactivated in the reac tion with peroxy radicals. Kinetic characteristics of the reaction between polyphenol sulfides and CHP are determined. Dithiolthione catalytically dec omposes CHP and reacts with n-decyl hydroperoxide DHP in the stoichiometric ratio.
