Abstract
Hydroperoxides are decomposed by contact with metalloporphyrin coordination complex catalysts in which hydrogen in the porphyrin molecule has been substituted with at least one nitro group and may be further substituted with other electron-withdrawing elements or groups, for example, halogen or halocarbons, or with hydrocarbon groups. Preferred catalysts are iron tetranitro-.beta.-octaethylporphyrins and iron tetrakispentafluorophenyl-.beta.-nitroporphyrins.

A process for the decomposition of organic hydroperoxide which comprises contacting said hydroperoxide with a catalyst comprising:
- ##STR9## wherein M is selected from the group consisting of Fe, Mn, Co, Cu, Ru and Cr;
- at least one X is nitro and the remaining X are selected from the group consisting of hydrogen, nitro fluorine, chlorine, bromine, hydrocarbon and halocarbon or combinations thereof;
- Y is selected from the group consisting of hydrocarbon, halocarbon, fluorine, chlorine, bromine and hydrogen or combinations thereof;
- and A is anion or is absent.
A process for the decomposition of organic hydroperoxide which comprises contacting said hydroperoxide with a catalyst comprising:
- ##STR10## wherein M is selected from the group consisting of Fe, Mn, Co, Cu, Ru and Cr;
- at least one X is halocarbon and remaining X are selected from the group consisting of hydrogen, halocarbon fluorine, chlorine, bromine and hydrocarbon or combinations thereof;
- at least one Y is nitro and the remaining Y are selected from the group consisting of nitro, hydrogen, fluorine, chlorine and bromine or combinations thereof;
- and A is anion or is absent.
A process for the decomposition of organic hydroperoxide which comprises contacting said hydroperoxide with a catalyst comprising:
- ##STR11## wherein M is selected from the group consisting of Fe, Mn, Co, Cu, Ru and Cr;
- at least one X is nitro and the remaining X are selected from the group consisting of hydrogen, nitro, fluorine, chlorine and bromine or combinations thereof;
- at least one Y is nitro and the remaining Y are selected from the group consisting of nitro, hydrogen, fluorine, chlorine and bromine or combinations thereof;
- and A is anion or is absent.
