FIELD: chemistry.
SUBSTANCE: method includes the following steps: dissolving chromic anhydride in water; adding to the aqueous solution of chromic anhydride, a tertiary alcohol comprising at least 4 carbon atoms and a hydrocarbon solvent; reacting the alcohol and the chromic anhydride at a temperature ranging from 20°C to 40°C by subjecting the reaction medium to low pressure conditions in order to distil the water; recovering the catalyst in the form of a chromic acid ester in the solution of the hydrocarbon solvent.
EFFECT: method enables to obtain a stable solution of a catalyst for deperoxidation of alkylhydroperoxide with very good efficiency and high output.
