PEROXIDE DECOMPOSITION CATALYST

摘要

This invention relates to a method for the catalytic decomposition of peroxides, wherein the peroxide is decomposed by means of one or more dioxo- compounds selected from the group of diketones, dialdehydes or ketoaldehydes having a calculated reduction energy (CRE) in the range of from -10 to -30 kcal/mole, the CRE being the energy difference in kcal/mole between the lowest energy conformations of the radical anion and the corresponding neutral molecule as calculated by means of the Turbomole Version 5 program. The present invention also relates to the formation of radicals by means of catalytic decomposition of peroxides using any of such dioxo-compounds. The radicals so formed can suitably be applied in any application selected from the group of radical polymerizations, grafting reactions, bleaching, drying of alkyds, epoxidation reactions, sterilization processes, and desinfection processes.
