Phosphororganische Antioxidantien. III. Kinetik und Mechanismus der Cumylhydroperoxidzersetzung durch cyclische Phosphite

Cyclic phosphophites catalytically decompose cumyl hydroperoxide, producing phenol and acetone, with the mode of reaction depending on the hydrolysis behavior of the cyclic phosphates.

Transformations of phenolic antioxidants and the role of their products in the long-term properties of polyolefins

Phenolic antioxidants play a crucial role in maintaining the long-term properties of polyolefins by undergoing transformation mechanisms that inhibit oxidation.

Mechanisms of antioxidant action: reactions of phosphites with hydroperoxides

Cyclic phosphites show different antioxidant properties, with o-phenylene phosphite showing the most activity and ethylene isopropyl and isopropyl propane-1,3-diyl phosphites showing similar behavior but different first-order rate constants.

The reaction of phosphites with sulphoxides

The basicity of phosphorus atoms in phosphites plays a crucial role in determining the reaction process with sulphoxides, leading to various phosphates and phosphonates.
