Abstract

Cumyl hydroperoxide has been decomposed using zinc O,O-diisobutyl dithiophosphate. The decomposition reaction consisted of three stages including the first homolytic decomposition and the last heterolytic decomposition. These decomposition modes depended considerably on the relative concentration of the complex to the hydroperoxide and the total concentration. From these results and on the basis of decomposition reaction in the presence of both zinc O,O-diisobutyl dithiophosphate and bis(O,O-diisobutoxyphosphonothioyl) disulfide, it has been shown that the formation of sulfuric acid was most important for heterolytic decomposition.
