CATALYST, METHOD FOR PREPARATION THEREOF, AND A METHOD FOR COMPLETE OXIDATION OF PHENOL Russian patent published in 2005 - IPC

Abstract RU 2256498 C1

FIELD: oxidation catalysts and waste water treatment.

SUBSTANCE: catalyst than may be used in hydrogen peroxide-mediated oxidation of phenol in waste waters at 50-70°C is based on montmorillonite clay and iron and aluminum ions intercalated in the form of polyoxometallate cation [Al₁₂FeO₄(OH)₂₄(H₂O)₁₂]⁷⁺. Complete oxidation of phenol into CO₂ and H₂O with hydrogen peroxide is effected in presence of above-defined catalyst, which is characterized by low degree of washing-out of active component into solution, at 50-70°C, preferably in aqueous solutions with acidity close to neutral.

EFFECT: reduced expenses, simplified preparation procedure, and achieved environmental safety.
